I also like the voice acting, though Knuckles and Big are pretty lifeless and boring (Seriously, Knuckles always sounds like he's narrating! It's actually kind of funny). The Sonic, Tails, and Knuckles stages are a lot of fun, the music is awesome ('It Doesn't Matter' was my anthem growing up), the story is engaging and never talks down to the audience/gamer, and the cutscenes are fun and campy. I mean, it plays EXACTLY like the DX version only with HD graphics. I mean, it plays EXACTLY Sonic Adventure: DX, the first 3D platformer I ever owned, how does it hold up now? Well, pretty well if you ask me. Sonic Adventure: DX, the first 3D platformer I ever owned, how does it hold up now? Well, pretty well if you ask me.
