once you get familiar with crap like THAC0, no role-playing rules will stand in your way.
i was never a big star wars roleplayer, largely for the same reason i wasn't a strong Aliens roleplayer. I didn't really have a lot of fun with licensed games. everyone wanted to make thin amalgamations of the heroes of the properties rather than just playing in the sandbox that was that world.
my favorite world was probably Torg, but the rules were shittastic.
