And certain online chatrooms. But they tend to be less dice-intensive, and more writing.
Which is fine with me. :)
Planescape Fanatic
"Fiends and Undead are the peanut butter and jelly of evil." - Me "That attitude should be stomped on, whenever and wherever it's encountered, because it makes people holding such views bad citizens, not just bad roleplayers (considering D&D was structured as a 'forced cooperation' game, and although successive editions are pointing it more and more towards a me-first, min-max game, the drift away from 'we all need each other to succeed' will at some point make it 'no longer' D&D)." - ED GREENWOOD
I have tried to participate in online play but so far it always fell apart in the planning stage. Don't know if I would have time now. One style I admire for the PBEM is Brian K Flood's. Check out his journals here at Candlekeep (http://www.candlekeep.com/campaign/logs.htm). I have volunteered at one time to try doing NPCs for his email campaign but nothing came of it (of course I haven't updated him as to my new email address but it was very long ago and the email change is very recent).
A friend of mine uses OpenRPG stuff (http://www.openrpg.com/) and seems to have successful games with far flung friends. I've been wanting to stop by on him and see how it all works.
