Oh, and I've had the misfortune of playing both Sonic and Shadow's campaigns up to Flame Core, and Silver's up to that Tropical Jungle thing, so no, you can't accuse me of bashing it before playing it. All the complaints about the game are entirely true, and far worse than the complaints made them sound.
About the only nice thing I can say about the game is that it LOOKED like it could have been a good game, if it had another year of development to work out all the bugs. Although we'd still have that SonicXElise romance that never should've happened (and, thanks to the convenient time warp at the end of the game, never did).
