Is there a MMORPG that is currently out or currently being worked on that replicates the actual experience of tabletop roleplaying?
I can't think of any.
The Pathfinder MMO won't even be replicating the the Pathfinder RPG rules, as the OGL won't allow it. So, it's Pathfinder in name (and possibly setting) only.
Heck, I'll lower the bar. Is the are multiplayer computer RPG that effectively simulates tabletop play?
Inquiring minds want to know ;)
