We all know right now that Sonic 4: Episode II is on the horizon.. but there is the possibility of a main series game releasing this year, or most likely in 2013. Some people want a Sonic Adventure 3, some want an HD port of Colors, some want SEGA to remake Sonic '06, or make a directors cut of the game. Tons of ideas are abound right now. But I want to see YOUR opinion on what you want to see for the next Sonic game.
What I would like to see for the next Sonic game is a fully 3D Sonic game, with no 2.5D sections whatsoever. I would like the game to have a good mix of exploration, platforming, and speed altogether. And let Sonic power up his abilities, giving the game an RPG-like feel, sort of like Sonic & The Secret Rings, and what was Sonic '06 was going to have implemented. And a story, going between the boundaries of lighthearted, and serious.
So, yeah. Discuss what Sonic game you want next.
