I am posting this as Windows as although a Mac client hasn't been ruled out, I'm guessing the chances are slim. I don't know if anyone is familiar with Dark Age of Camelot but the same person who created it is making this game. So far it is shaping up to be a sandbox MMO that will have a heavy PvP focus, heavy crafting focus, horizontal leveling and what looks to be a pretty awesome building system. Right now, it is in the kickstarter stages but I'm hopeful that i'll be funded. I'm at the stage that I refuse to play any game that isn't OSX but I think I'd make an exception for this game.
