The system that I am using started as a 2nd edition homebrew to make it more accessible to people ( no more use of the word THAC0 and increasing AC ). But I soon started modifying more and more and ended up with a system that is very loosely based on 2nd edtion rather than 2nd edtion with little modifications. If you think you might be interested in playing a game with this kind of system (and by all means PM me and I will send you the full rule-set if you wish to read it) then check out: <a href="https://app.roll20.net/lfg/listing/11083/heavily-homebrewed-sandbox-game-system-based-of-ad-and-d-2e" rel="nofollow">https://app.roll20.net/lfg/listing/11083/heavily-homebrewed-sandbox-game-system-based-of-ad-and-d-2e</a>
