Here is a list that I've compiled so far for AD&D 1E resources, Free or Fee wise. This list will be updated every so often, so come back and check it out! I will try to keep the links updated, but sometimes things happen!
First I want to say, I think online gaming is a great tool for gaming and while its been around for a long time, in these last few years, playing on line has become so easy, its almost the same experience as sitting at table with your friends in person playing the game. DM's can post up their game, allow people to read up on the game and decide if they want to join based on the DM's rules.
Something that has always bugged me in D&D and this dates back to the days of playing D&D in the '80s, but its more of a thing since the "MMO/video gamer generation" (let's go with that for now) has moved into playing D&D, was that all their stats have to be high, and anything less then having a +2 modifier on your stats was a "waste of time".
