I bought Other M
used and only for $5. I still feel kind of ripped off.

Edit: The game does, thankfully, get better after that first hour [which was painfully in every way imaginable], but it's still far, far from being good. It's a mediocre action game wrapped in a dumb story acted by awful actors. Nearly every aspect of the game is designed to be as simple and easy to understand as possible. There's virtually no exploration, the game tells you exactly where to go and there's pretty much one way to get there, but, oh, you might have to bomb a clearly visible crack in the wall to get past a locked door. The dialog is banal, boring, and overwrought, with every plot point repeatedly bashed over your head in cased you the mountain of visual clues. The combat involves, mainly, smashing the "2" button while smashing the D-pad. But they did try to liven things up a bit, by having you shift the orientation of the controller [and go into first-person mode] to use missiles and such, which also makes it impossible to move. There's also very little environmental music, and what is there isn't particularly great or memorable.
