SONIC HEROES
Shadow the Hedgehog
Sonic Adventure: Director's Cut
Sonic Adventure 2: BATTLE
Reasons! (How can I rate a game I've NEVER played?)
Why Heroes wins me over: Lovely GFX, SFX (Including Music) Super Fun to play, Awesome boss fights, Zone-by-Zone progression-Need I say More?
I enjoy Shadow the Hedgehog because: Multiple paths, easy levels, great music, fun boss fights and the Chaos Powers. (I normally don't like FPS's, but I'll make an exception here)
How Sonic Adventure DX is great: Unique Gameplay, good music, and how SADX plays like a classic. (Only played the Trial-I think 1 beats 2)
I've never played SA2B. Sure the story is good, but the music of the game is everywhere, which I find quite annoying. But I can say that the boss fights look fun.
