I've started running the starter adventure on Eclipse Phase. I have an idea for our first full-length campaign, but it's a little complicated. I need a (relatively) simple game to play the part of a computer game that the PCs will play either:
a) To advance the story and gain experience
b) To kill time when someone can't make it to the session.
Most of my players have some D&D experience, so it would be nice to have a fantasy setting. I was looking at Anima, but reviews seem to be ambivalent at best. Maybe I was just dredging up the bad ones, because I read some of the core book and liked what I read; at least half of them are also fans of animé. So, requirements-wise:
1) d100 or d20 system for compatibility
2) Some fantasy elements; mostly I want leveling and exceptional PCs
3) Something that feels a bit like an MMORPG. It is supposed to be a computer game within the game world.
