For systems I really miss playing TSR's non-SAGA Marvel (don't know what the system was called or when it was released, but it was the one that had the FASERIP stats), it was so easy to be mindlessly over the top in that game.
Not a system, but a setting I wish had caught on was Engel. Distributed by Art Haus, it was the perfect mariage of d20 mechanics and a great almost WoD setting. The only thing I didn't like (besides not finding players) was the second tier of angelic power skills that you had to buy with the same skill points as the rest of your skills.
