Shadow the Hedgehog.
Twice, actually. There are ten different endings. O_O It took me around seven hours to beat the hero ending, and about 2 to get the normal (which...was actually rather depressing) ending. XD Endings 1-9 are, in fact, all depressing. The hero ending is good, if cheesy. But the annoying thing is...after you've beaten the game ten times, you get the REAL eleventh ending...I can't decide whether I'm impressed or annoyed about that fact. As it is, I just looked it up and read it...I'm uncertain I liked the game enough to beat it eleven (the final ending has a bonus level) times.
Anyway, the game was a combo of frustrating and awesome. Frustrating, because the speed aspect was killed during the hero/evil missions, as you had to stop and complete objectives...which meant you had to deal with a camera bordering on terrible (it would simply stop working at times. Usually during a platform segment) and combat that was just OK. The speed though. Oh the speed. The normal missions (of a choice between hero, dark, or normal) were just running through a level, wreaking havoc if you could. And they were awesome. XD So, so fast.
There's also several hundred uses of the D-word. Shadow says it frequently in dialog, whenever you get hit, and whenever you die. Literally, every time you get hit. I 'spose that depends on how good you are though. XD They also removed the Sonic standard of "get hit, lose all your rings". It's been replaced by a far better system of losing five rings per hit. And not to mention the really funny/lame lines and talkings...but that's expected.
