Just wondering if I can play any PS3 games besides UT3 with keyboard and mouse.

From what I know that's the only game that has KM support unfortunately.

looks like you might be interested in this little doohickey.

Do you know if the mouse emulation on that is any good?

I don't think it has mouse emulation. From what I've seen of it, it just converts mouse movement to the equivalent joystick movement.

I had wondered about this a while ago because I'm so used to playing FPS' with mouse and keyboard. If I can find a PC version of the game, I'd get it. But if it's a PS3 exclusive, like Haze, then I'd be stuck with the Sixaxis. I was thinking about getting either a Fragenstein or Split Fish, but there are two, equally divided camps on which is better, and it's making it impossible to decide. I've been bugging the hell out of the local GameStop manager to get display models of both so I can try and decide for myself, but she won't.

Nope, you can't. Buy a PC instead. FPS genre is a WSAD business :-P
