These are just a few of the titles I thought of first, none of which I have ever played. There are still others, such as Bomberman Fantasy Race, that I used to own and wouldn't mind getting a chance to play again.
Since I can't decide, I open the floor to you, lovely readers, for suggestions! I'm sure most of you reading this already know my gaming tastes, so hit me with your best shot! I wouldn't mind some PSP games, either. If I end up picking one of your suggestions I'll dedicate a post to it, with a special shout-out to you, as well.
