I'm not sure simulation even ranks second for me. (Although, like everybody else, there are places where a lack of realism gets under my skin.)
But, yes, between those two things that's the order.
I just can't muster any outrage over, for example, martial abilities being 1/day. Why is it 1/day? Game balance. How do you 'explain' it? That was the only time that day that the hero could muster sufficient ferocity. Where's the problem?
I never said it was a particularly good set of rules for simulation of a fantasy world. Obviously things have to be simplified to work as a game, and D&D has always been more "action movie" reality than the real thing.
It's just the most enjoyable set of rules I've used for my goal of simulating a fantasy world.
