A good game depends on the opinion of the gamer. I think Sonic Generations is a good game because it includes the classic game play of Sonic which I enjoy and also includes the classic characters of Sonic, which I enjoy playing as, and the game is fun to me overall so I believe it is a good game.
This game... This game is one of Sega's masterpieces. It can be glitchy at times, but Classic Sonic with Modern Sonic was a game that Sonic fans wanted for years. I personally love Modern City Escape's new truck chase. It starts out the same, but then the truck explodes with weapons and you'll be freaking out.
