What do you look for in an RPG? What should it accomplish for you? What should it feel like to play it?
It should inspire me in such a way that I feel hundreds of hours of inane plotting and longing-to-be-retired game systems are worth slogging through. Generally that inspiration takes the form of “there is something amazing out there, somewhere — and lots of lesser wonders, that are up to me to realize”. And I should feel like every one of those discoveries (material or not) is a victory won, in its own right. A personal accomplishment.
Actually, uh. That’s the way I approach just about everything in life. So.
