Shadow the Hedgehog. I'm one of the staunchest supporters of 3D Sonic, as Sonic Adventure 2 is my 2nd favorite game of all time (behind the incomparable Metroid Prime), but the story is so laughable, aside from the sheer aesthetic collision of guns and aliens and killing human soldiers in a cartoony game
Plus the branching storyline was incredibly addictive. Mix and match and mix and match, again and again and again.
