Paranoia and Teenagers From Outer Space were both seriously crazy games, and were so mentally taxing that I could only play them about once per month.

Most of the rest of the time, I played the West End Games version of Star Wars RPG, or Marvel Super Heroes RPG, or sometimes the Amber RPG.

More recently, it's been primarily the FFG version of SWRPG, online via Roll20.net.

I loved that game. Most amount of humor in a game I ever saw. Wish I cold find someone to play with these days.
