I have played a lot of SW revised core rulebook. for me the biggest problem was that to use force powers it took away health. that just never made sense. recently i was searching the net for a better magic system for dnd 3.5 and stumbled on something that i think would be great for star wars with a little tweaking, ok maybe a lot of tweaking but the general idea i think would work really well if built for star wars force powers.
Its a strain system, basically your body can only handle so much magic/force flowing through it at a time.
Here is the link its better than me trying to explain it ;-p
