Hmm. 90% Dom2 and Diablo 2; a little Anacreon and Angbands.
I keep meaning to get back to an RPG - Diablo sates my appetite for meaningless, mindless slaughter and accumulation of treasures (Hardcore only, so the treasures actually mean something), and Dom2 my crafty, strategic powermongering side, which rates right up there with such legends as Bobcat Goldthwaite.
I keep looking at what new has come out, looking for a new fix (hard to get back into the older ones I've had a few years - not that they're not great games, but starting over from scratch from reinstalling or trying to remember what the heck I was doing in some of the larger console games isn't fun).
