i disagree, Colors, Generations, and both Episode 1+2 were very good.
Unleashed too if it weren't for the damn night levels -_-
Colors and Generations are only good compared to '06 and Unleashed. They stand no ground on pre-HD Sonic. Way too much automated sequences in areas that didn't need it, down to the springs automatically taking you the direction of the goal. A good game would give you the freedom to explore, especially in Sonic where they hide easter eggs and secrets in secluded areas.
I haven't yet played 4: Episode 2 outside of the demo, but all 4: Episode 1 boiled down to was ruining the classic stages. All the stages and boss fights were pulled directly from Genesis games, revised to HD, then added the new Sonic gimmicks to take out the freedom and lower the difficulty. So in my eyes, the only thing they succeeded on with it is the fact that Sonic's best days were in 2D era. Sadly, the game wasn't a sequel, nor did it stand anywhere near as good as it should've.
Facts of one whos never played the game, and thinks he knows what he's talking about.....Gfaqs, "sigh"
Its commonly known on Gamefaqs that if anything is more evident than proven facts, its personal opinions.
