Anything beyond 60 fps is really gravy. The only reason to shoot for 120, is that when you hit an area that might slow down, that you don't dip below 60.
I don't understand the people who said KOTOR was the greatest game of all time. I enjoyed it, and recommend it. It was a pretty good game the first time around, but it's far from perfect.
Maybe I'm the only one who felt this way, but replaying KOTOR:1 at all felt like a chore for me, and I didn't finish my second play through. My wife played Female DS, so I got to see that story without playing it again myself.
You can select the workbench with other characters, but I believe only the main PC's repair skill is really being used, and I could be mistaken.
Actually the skill depends on what you are breaking down.
