I would like to give my view on the current trailer.
I was uninterested in early trailers of this game but this specific one have my curiosity. One important details the has allowed me to become interested was the unaltered gameplay camera. We finally get to see sonic in action the way he suppose to be viewed. Now that the game can hold it action/thrill appeal without a modified gameplay camera let talk about what I saw.
The speed is faster than I was expecting and it does look......hard, especially the jungle level. A hard looking game isn't necessarily bad, but without focus on level as well, I believe many may become uninterested. This trailer focused on killing enemies.
I see some people like the ability to knock enemies into each other. I'm not really impressed, due to being capable of this in Unleashed and Colors. The eagle wisp looks rather simple and neat, I sense many hidden secrets that require this powerup. Most enemies look un-engauge to what sonic is doing. Some are waiting to be killed which should hinder their sense of threat even to causal. This will likely produce the mindset "Kill the enemies in a special way" but to a lesser degree than sonic colors due to their placement.
