I love tabletop RPGs, but I don't have the resources to go out and buy rulebooks and DMing guides and kits. Are there any free (open-source, for lack of a better term) D&D clones I can get my hands on? I'll mostly be playing with friends online via chat.
If not, are there any resources/skeletons out there for creating my own? I know "just use your imagination" is a tempting road to go down, but most people don't appreciate the planning and intricacies that go into these games - I can't just sit down with a glass of wine and pull something worth playing out of my ear.
Any advice and/or opinions are appreciated. Thanks in advance!
