Well, after several hours I have the gross motor control slightly working for me. It's still far from instinctive and I go backwards quite often. I have to think to look around sometimes. Fine motor control is basically zilch. I can't fire with any level of accuracy, much less land shots on a sub target (like a head). It only gets worse when there's a lot of movement. I end up eating a ton of enemy fire while I try to slowly draw my reticle over enemies... often point blank.



Now we just need more games to support keyboard & mouse support like Unreal Tournament III on PS3 (crosses fingers...)
The problem is that this requires way too much extra work from a developer standpoint. For online play you've gotta be able to recognize the control scheme and keep the key/mouse people separate from the controller people otherwise the key/mouse people are going to massacre the crap out of the controller people and gamers are going to cry fowl.

There's just not enough reason for most developers to set up something like this on top of the fact that you're asking people to buy extra peripherals for superior controls.
