A couple months ago I ran a FUDGE game of Star Wars at a local gameday. It went VERY well. Of course, I learned a lot about how to tweek my version of the rules to make things run smoother next time. I run a fairly lite system, 2d6, roll under your level (I mapped the FUDGE levels from 2-9). This is similar to what Stephen O'Sullivan does these days for some games, as I understand it.
One thing I found was that combat ran much quicker than some other games, we got a LOT done in the four hour session (I was exhausted as a GM at the end). A few players also told me how surprised they were at the amount of roleplaying during the game. Not sure if that is just my GMing style, or because FUDGE allowed for quicker task resolution.
Just wanted to post to let you know that FUDGE was getting some playtime. I've run two sessions of Star Trek using it too.
