Gee, you really think so?And I don't understand how you can counter this with the fact that Sega/ Sonic Team wasn't directly involved with development of some of those games, because they're not directly involved with the development of this game either.
EDIT: In fact, your entire argument against Sega's ability to "make a well designed and implemented game in 10 years" is now irrelevant because we know that Sega is not developing it. Just sayin.
EDIT 2: Didn't feel like responding to A and B because C was too funny to ignore.
