I've purchased my first MMO.

I've pre-ordered All Points Bulletin from Steam, hopefully it'll be worth the money. I was in the closed beta but barely played it, now that the open beta is out I'm enjoying it a lot more.

 I quite like the payment model as well, you can buy hours that only tick down while you are playing the game so nothing goes to waste. But if you think you'll be playing the game more than 20 hours a week or so then you can buy a standard subscription like other MMOs. I'll play my 50 hours that were included in the pre-order before I decide what to get, if I'm even playing the game by then that is.
I only know one other person getting the game though, so if any Giant Bombers would like to play with and help a first time MMO player, that'd be awesome of you.
