I find detailed and time-consuming tactical combats boring.
Same here. I played Warhammer (Fantasy and 40k) for years and one day realized that I was not enjoying it at all. I enjoyed the back story, but the actual gameplay was horribly repetitive and dull.
I've only played in one D&D game in which miniatures were used. It slowed things down and completely destroyed any attempt at imagining the action - I was too focused on how many squares I had to move or whatnot.
Anyway, I'm going to pick up some of the 1e books over the next couple of days. Obviously the DMG and PHB are necessary, as well as Oriental Adventures because it was my first foray into roleplaying. Anything else you would suggest?
