Yeah, it may be a weird question, but with some of the recently released high profile RPGs (Monsters & Magic, FATE Core, Numenera) there are many an OSR gamer that will be looking under the hood of other game systems with different assumptions than "classic" play.
What do I mean? Generally, in an OSR game, the two general assumptions are "let the dice roll what they will" and "Rule Zero" - the DM will make decisions for situations that aren't explicitly spelled out by the rules.
Basically, the dice rule and the DM rules and the game proceeds, often in unexpected directions, and randomness can be an awesome thing. The game leads to the story.
My general gut feeling (and it is very general) is that the recent releases listed above put the story before the game. Even Numenera has aspects that, upon a quick perusal, remind me of what is generally referred to as "storytelling games".
Eh, I'm getting crotchety in my old age. Change means new learning, and new learning aint as easy at 46 as it was at 16 or even 26.
Still, the new games are sure purty to look at ;)
