Greenmangaming had this on their site the other day and you could use coupon codes with it. I think the one I used expired at the end of July but ended up getting this for like $45 which is a pretty good deal IMO considering there's no monthly subs and the game seems fairly meaty.
I thought it was a blast, enough riffs on the usual MMORPG stuff so that veterans are comfortable but enough new innovations to keep things interesting. I really liked their take on out of party co-operative play, its something that MMOs in general have needed for a long time. The events that unfold around you run the gamut from usual escort stuff to holy fuck world boss with 200 people fighting and all sorts of crazy shit going on. The PvP was a total hoot too and you can earn exp for leveling and stuff that way which was nice.
My big concern is that the launch might blow up in their face. Most of their stress tests have been in the ten to hundred thousand player marks and sim tests only take you so far. They really should just have a truly open beta for a few days to play it safe. Blizzard thought they had the Diablo 3 launch nailed and look how that turned out.
