I ask, because I'm not even sure if I have one. Well, there is Tunnels & Trolls, but that is still fantasy and stripped down to it's history, very much "D&D".
I've heard much goodness about Savage Worlds, but I think I'd really need to play in a few sessions to really wrap my head around it. Ubiquity (Hollow Earth Expedition and others) seems almost like a stripped down Savage Worlds. FATE just makes no sense to me, even if I did support the Kickstarter and have endless support for it. Yet another game I'd probably have to play in order to grok.
I guess I don't have a "go to" non OSR RPG.
So, what's your game to play when you're not playing OSR?
