Italian d20

Yeah, pretty soon, Cinder's about to give Vrill all his cash and magic items and apologize for being a dick to him all these months. And then politely stand 30' away preparing for a fireball. I give him til this weekend.

Anyway, check out these sites:

I think these are descriptions of table top games though. However, there are also many sites that run games, sometimes multiple games, on forums. Some of the sites you've linked us from are like that, or have long lists of such sites. I found nothing quite like DnD though.

And the Italian thing is awesome. Check out that d20.
