Of all the features I'd like to see in UT2007, an updated code base for the Pawn class and various physics modes (walking, falling) is at the top of my list. First of all, the way it is now, it's totally unintuitive, bearing little resemblence to reality, and has so many cheap hacks baked into the code (like Z being hardcoded as up for most things) that workarounds take for-frikkin-ever. Even worse is the fact that the code for the physics modes is not at all accessible, and it was never released to the public by epic, so if you want to do something fun like wall-walking, you're stuck trying to work around Phys_walking or fiddling with Phys_spider. ANYWAY, I'd just like to see the damn thing overhauled and replaced with more consistent, friendly, moddable code.
