So if you want to try one of the games that start it all, give it a try. Just a word of advice, don't mind the graphics, it's an old game.
Before getting into the game, i would also advice to give a few browsing on the official foruns for some info on classes and what to do, because you can get really lost fast there. It's a bit daunting at start for a new player.
Anyways, go here and start the adventure, if you are ready for it!
