Generally when people play tabletop, they want to play it with a group of friends they already know. Even if you have a bunch of roleplayer friends, chances are they aren't going to know one another that well. It's always fun to just joke around with people in between attacks or scenes, so. Plus tabletop is generally meant to be played in real time rather than waiting on someone to post. But hey, it still works on the site. I'm running one right now.
