I still play AD&D2e, because I'm old-fashioned and trapped in the past. And cheap. I have a Player's Handbook for 3.5, and am fairly familiar with it, but when I DM it'll always be in 2nd Edition, unless I get really desperate. Then I'll prolly read the 3.5 handbook and fall in love with it, because I'm fickle like that.
So, yeah. I love 2nd Edition, and I'm okay with 3.5, but I'll still prefer 2e over the newer versions.
