I actually finished Paper Mario: The Thousand Year Door yesterday. :P (For the second time.) Lots of fun, that game.

The only two games that come to mind are Second Sight and Skies of Arcadia. I'm playing Skies of Arcadia now. It's a very unlucky game. :P Whenever I've tried to play it through before, I've enjoyed it, but stuff has always come up to make me forget about it.

I don't like Second Sight so I'll probably never finish it. xP
