Heh, I've got one shelf stacked up with AD&D 2nd edition stuff, all the core books, and nearly the complete boxed sets and supplements for Al-Quadim, Birthright, Dark Sun, Forgotten Realms, a chunk of the Planescape and Spelljammer... Although it's been about 6 years since we last used any of it.
That annoying time when the group that had been playing together for a decade plus ends up scattering around the country and dealing with jobs, marriage and suchlike..
I still pick up new rpg books, but I've found it tends to be more for my own personal reading and occasionally doodling of ideas rather then getting actual gaming in with a group.
I totally hear how life can completely get in the way of old school RPG! You said you picked up new books. For AD&D 2nd Ed?
Heh, no, I think I've nearly got practically complete set of Ad&D 2nd edition stuff all stacked up.. I tend to pick up new books on fresh rpg's and such. Of late it's been more Shadowrun, M&M, Eclipse Phase, Pathfinder.
I did go through a lot of WoD before the new edition. (I think if I put all my Vampire/Mage/Demon books on end I'd get a pile about 5 foot high).
Fresh new worlds and settings that can be interesting to see how they've handled different issues, and see how they've approached similar mechanics in different ways.
Hey I got Eclipse Phase as well. Nice setting isn't it? The rules are a bit clunky though
