I would like a Mario&Sonic platformer or adventure game, but there is a problem...

[TheOgGamer]

I think that making Mario and Sonic two separate characters in a platformer game is impossible, unless you don't make Sonic slow or Mario extremely fast

This here is the entire reason why your idea is so restrictive. Let me tell you something, do you think a general gamer just looking for a wii game, and this happens to have Mario and sonic in it, will care about that? Do you think fans of Mario and Sonic Olympics, a game where anybody has a chance to beat sonic, shadow, or metal sonic in a foot race, will care about that? Do you think a parent buying their kids a new wii game and sees this, will care about that? I'll leave that answer up to you, but the only people who will care that much are hardcore fans of either franchise, but we aren't the only market here, think about that.

Besides that, your not leaving any options for players, and throwing to much strategy into something where it isn't even needed. Combing attacks would be cool, but it should be left up to the players on who teams up, and what it is that they do, not to mention that you don't even seem to be regarding the prospects of multiplayer, cause it seems you want sonic and mario to be as one character as if this was sonic heroes. I'm not saying your idea doesn't work or that it sucks, but your letting you own ideals of what you think the characters need to be like get in the way of variety and creativity.

I mean, lets forget the ideas here for a second, what are your plans for multiplayer and other characters? Can player 2 join in and be able to pick who they want? What if they wanna team up as Wario and Knuckles or Yoshi and Shadow for instance, what does that do with your plans of having to balance mario and sonic when out of the picture, and how much more fun do you think it'll be if 4 players are in one room, but have to wait because the game is on 2 players, if you even allow that? Come man, give your players something, this is a sonic and mario adventure, 2 big name characters who have had great games in the past, coming together.

I'm not making a game to sell it to someone who have to enjoy it, I am not even making a game, I actually just explained some of my ideas on how to mix Mario and Sonic's 2D gameplay. What I described is not a game, they're just some gameplay mechanics.
Multiplayer, other playable characters and plot, are secondary things, I just wanted to mix the two existing gameplays into one.
If my interest was to make a completely new gameplay with Mario and Sonic, then I could have had any idea you want, but that was not my goal.

My goal was to ideate a gameplay that isn't Mario's nor Sonic's gameplay, but it's both of them, based on their classic 2D platformers.
And you know that this most likely is never going to happen, not from Sega or Nintendo, because Nintendo will never allow Sega to do it, so mine are just ideas wich I had for fun, nothing serious.

Anyway, what I said is just a small part of the idea, since I sketched it on a diary with a pencil.
And trust me, with that gameplay, the player has the same freedom as he has playing most of the existing 2D platformers; all depends on how you make the level design, since the moveset allow you to do various things and gives you a lot of choices.

If I said you "I want to make a game with a plumber as only playable character, that jumps on enemies to kill them, and have just 3 power ups, then you have to repeat the same pattern of levels for 8 zones" then what would you have said? You know how successful the first Mario game was.

Hey, if that's how it is, fine, but you said makin such a game is impossible because of gameplay. What I was trying to do in my post was to challenge that, something a lot of people in this fanbase wont do, which doesn't help with video game designing, which leads to us having mediocre titles like M&S Olympics, a game popular only by those 2 names, because I guarantee you that Nitendo could've made the same game alone just by making it a wii party game like those other titles, with the only thing being effected is sells.

My goal was to ideate a gameplay that isn't Mario's nor Sonic's gameplay, but it's both of them, based on their classic 2D platformers.

So both of them playing separately through platforming and other challenging levels wouldn't mean the same thing?

And you know that this most likely is never going to happen, not from Sega or Nintendo, because Nintendo will never allow Sega to do it

I well aware of that, and it's one of the reason why Nintendon't sucks compared to Sega, or how Sega use to be anyway, back when they came up with that slogan. Honestly, the few times their any good is when making Super Smash bros. Think about it, Nintendo had their heads in the clouds with the Wii's success, that they let all these 3rd party developers create nothing but shovelware titles and uneeded games based on movies, like balls of fury(and yet fans hated black knight), and now many gamers are ditching their wiis. Sega was one of the few developers still putting some thought into at least some of their titles for it, like the conduit, and one of the few times they didn't try for a full game was.... wait, what's the of this forum section again? Yeah.

so mine are just ideas wich I had for fun, nothing serious.

but how do you expect to have a good idea if your not serious about it?

Anyway, what I said is just a small part of the idea, since I sketched it on a diary with a pencil.

but what about multiplayer and character choices? Having a good moveset is nice, but like I said, what if people would like to be other characters, and what if more want to play? See, this isn't anything against you, but we have many sonic fans who can blurt out what games suck and what games should be made, but many of them don't even take the time out to come up with detailed ideas to support their theories, unless it's how a classic game could work, and how a game with multiple characters can't. You have to think outside of that, but maybe it's because I'm a little more serious on the account that I've played many good games that I feel actually tried to do something, it's what makes them unique and stand out more then the rest. My idea here was add choices for multiple players, in a game that isn't just about being a party and being tied down, but being a party while actually having an adventure with some freedom.

If I said you "I want to make a game with a plumber as only playable character, that jumps on enemies to kill them, and have just 3 power ups, then you have to repeat the same pattern of levels for 8 zones" then what would you have said? You know how successful the first Mario game was.

That was back in the 90s on a primitive system that didn't have much to offer outside of that. This is 2012, a whole new generation of gaming, and on far more advanced systems that can offer us almost anything we want, like being able to do what you just said, but with 3 other people playing with you, and 3D graphics. Let's just say this, how do you think of the first super mario bros would've did if it were fist released in this generation, with 8-bit graphics, music, and limited story?

[Iko]

Sorry, I'm a bit busy, and actually I can't reply to all what you wrote, but I can reply to something:

I said it was very hard without twisting them too much, I didn't say that it was impossible.
I said that a solution could have been found with some creativity, and I gave you an example.
You took it too much seriously I think...

The videogaming would have been a lot different, I can't reply to this. Mario has been a great step forward in the gaming history, and if Mario was not released, almost certainly Sonic would have not existed too.
The certain thing is that today Mario games sell a lot, even with no story and no multiplayer, and a small number of power ups (Mario 3D land).

Happens already, you should take a look on some released games most of them didn't achieve to take both core gameplays. Nearest example of combination of sonic and mario gameplay I know is Kid Kool(spiritual ancestor of psycho fox and decap attack)

sadly, kid kool is horrid.

Rayman Origins has fast paced gameplay and "jump on the bad guys to kill them" and "2 hits and you're dead" mechanics though. what about that?

Yeah, kid Kool is horrid.
Rayman Origins, it's much more mario, no core gameplay from sonic was taken.
What sonic core gameplay have it's the acceleration and add speed psychic. There is not even a non-sonic game who got this core gameplay right.

There is a reason because of what it's almost impossible to make a game with Mario and Sonic fighting together.
Mario usually fights agains monsters, wich very often are similar to animals. The same Bowser, he is a giant turtle, so the koopas and a lot of other creatures of the Mushroom Kingdom.
Sonic usually fights against robots. Usually, in Mario games, robotic enemies are rare, and when there is some, usually Mario is unable to destroy them directly: sometimes they have a weak point, sometimes you have to use a trick to hurt them, with a bomb or with other things, etc, but you can't destroy the metallic parts, usually (there are some exceptions, for example those small robots in Super Mario Land 1).
Useless to say that Sonic should defend and save animals, and in Mario's world most of the animals are usually enemies to hit and kill.
Making a game together would force the characters to do things that go against their nature and their games.
I think it's possible to find a solution for this, using some creativity, but I think it's hard to do without twisting too much the two universes of the two characters.

And that matters why? Enemies are enemies.

You're just thinking too much, nobody is going to stop in the middle of a game and think about the nature of them completing a boss.
