Dunno about that game, but I am playing around with a new(For me) game to try things out and I have found and joined a guild that, so far, seems to stay in roles, even though some of the names are... OOC. (Ex: Jason234, a really cool guy btw, and stays in character... but that name....) and they have not once asked me a/s/l or anything about my "real life" (kind of assumes I have a real life, and as many of you know, I am an NPC....

)
So, any game CAN be a RP-game, though none have come close, that I have found, to PS on that front. (In this newish game, I stay of world-chat, and stick to general tab or guild tab, to cut down on the OOC worldshouts... but I can ignore the "noise" of OOC as long as i do not have to respond to it ... )
