Players get 1 key to use for a buddy, gives a week of time. You need to use the buddies install discs though. If you don't, they charge you $3 for the download, but add on another 3 days for a total of ten.
So, this I did. I played for two days, then they locked my account because they think my credit card expires on 01-09 rather than 09-09 (like it says on the card and my account...).
So, I played it for a bit. Looks nice enough, patching was a pain, basic combat is decent enough, though I found I focused too much on basic attacks vs the combo/powers.
I'd definitely play it over Warhammer, it reminded me of Guild Wars in some ways. Warhammer was sluggish (not framerate, just gameplay) and just didn't appeal to me.
