And.. How is OT different? I worry it might not be "serious" enough, too many jokes and not much going on. But this is just from what read on the forums
OT is vehemently not serious. It's about as not serious as one can get:
http://wiki.battlemaster.org/wiki/Outer_Tilog_(Realm). Most of the characters are delusional and/or criminally insane. We have characters who believe they're skeletons, zombies, vampires, wolf-man - all the classic horror movie stereotypes. None of them, of course, can be anything but normal human according to BM rules, but that doesn't prevent them from living under their delusions.
It's great fun, but don't come to OT if you're expecting serious roleplay.
