Stang,
All MMO's that I've played to date don't offer discounts of any kind. My wife and I always have to buy 2 of every MMO and pay for 2 accounts. It sucks.
I'm currently paying for 2 Dark Age of Camelot accounts, a Neocron account, a Shadowbane account and soon to be 2 Planetside accounts and at least 1 Star Wars Galaxies.
Yeah, I'm gonna have to start cancelling stuff, it's getting out of hand!
