Me and my wife both did the 40.oo pledge. She's maniacal when it comes to crafting in MMO's, so this is potentially a reallly good fit for her. Salem is also an upcoming crafting type mmo too, but it has all-PVP all the time, which she has no desire whatsoever for. I can agree with her on that I guess, PvP is pretty annoying.
