Among the group, somewhere around 6:00 p.m CST is preferred. Though most of us are free completely on Saturday. The only things we ask is the setting still have it's roots in a traditional fantasy setting, you know: Mages, knights, kingdoms, and the like; and the campaign has to be roughly around 60% roleplaying (social interaction with npcs and PCs) and 40% combat (we still want to fight things). Otherwise the GM has full reign over the campaign as we are generally up for anything especially homebrew.
