I don't like D&D, and I don't like Pathfinder. I've played in great games, but i don't like class and level one bit, and really don't care to do all the upkeep it takes for crunchy D&D and pf characters. I like simple, but I also like old-school games that aren't D&D, which mostly means Basic Role Playing, the Chaosium house rules for Call of Chtulhu and Pendragon (kinda, sorta...). I picked up a hard-back of BRP last time I was in MFLGS, The Days of Knights, last Saturday, and daydreamed about running a Sci-Fi game.
Of course, my fisrt love would be old FASA Trek, a percentiles-based system, where you rolled up some things, but mostly roleplayed the chargen, if you had a smart GM, the thing I like most about newer systems like FATE.
But the main thing about old-school, was roll-and-scoot! If you needed a character, you played what the dice or an understanding GM let you have... miss that, a little.
