The only things I want from Kotor 2 (Xbox version) are:
1) A locked smooth framerate. Either lock it at 30fps or 60fps. I don't care, as long as it's smooth and constant. The framerate really bugged me about Kotor.
2) Better skies. The skies in Kotor looked pixilated and static, it would be nice to have beautiful skies with moving clouds. Most games today do this. Something like what Splinter Cell has.
If it has that, then I'll be picking up Kotor 2. (I'm confident gameplay and story will be great) If not, then I'll pass. In my opinion a solid framerate should come first, way before any graphical fluff. I don't think developers should sacrifice framerate for fluff graphical features. Personally I would take lesser graphics with a perfect framerate.
