Miniatures, maps, and dice are fun, and that is still the way I tend to run my library Dungeons & Dragons games. My non-work group has been moving more toward "theater of the mind" gameplay, though. We have been playing a system called Genesys which uses more abstract, descriptive terms for distances instead of the D&D "You're 30 feet (6 squares) away from the goblin."

As for war games, I find myself drawn more to smaller-scale skirmish games as opposed to mass battles. But I do occasionally still have the itch to play Orks in Warhammer 40,000 because they get to roll all the dice!
