I play AD&D, 3rd Edition and 3.5

Mostly Hack 'n' Slash, unfortunately, since my 2 of my roommates were more interested in finding loopholes in various Spells/Psionic abilities and utterly raping the combat system.

I suppose I have yet to play a true AD&D session, but that's ok.

I haven't DM'd anything major, and most of the characters I like to play are either Rogues or Rangers (I tend to think like a Rogue would).
