And being PC I won't be getting it anyhow, as I use laptops now and hate trying to play games with the touchpad. Now if there was a 360 version...
No one will think less of you if you bought a mouse or gamepad.
I've thought about plugging in a mouse - I wouldn't mind replaying some of the PC games I've got, but somehow it just doesn't feel the same as a proper keyboard/mouse combo. Something about where the wrist sits or the angle of it... can't quite put my finger on it.
