I prefer story over mechanics in a game. The crunch should be the engine that allows the story to happen and not vice versa.
Began RPGs with AD&D and D&D Basic. I have journeyed through many worlds using Rolemaster, Harnmaster, Shadowrun, Vampire the Masquerade, TORG, Palladium, Marvel Super Heroes, DC Heroes, Champions, G.U.R.P.S., Star Trek, Star Wars, Chill, Call of Cthulu, Runequest, Warhammer, AD&D 2nd ed, 3rd ed.D&D, 4th ed.D&D, and 5th ed,.D&D [Phew!]
I am interested in trying 13th Age, FATE, Dungeon World & Savage Worlds.
