if you just got it today.. and they gave you a 'early access/beta key'.. then you can play as soon as you install it (providing the server is actualy up)
I havent purchased it yet as I want to be sure that I can just download and jump on. Im not 100% sure I can with this site. Just wanna play the early access. I dont wanna pay/ download and then have to wait till friday otherwise I will just buy a boxed copy.
oooh yea.. well in that case.. Direct 2 drive works like this.... You buy the game from them.. they then take you to a webpage that lists ALL of your games you have purchased from them along with a download link and a 'activation' key.. That key is sometimes needed to 'unlock' the downloaded installer for the game.
with MMO's they usualy e-mail you a CD Key that lets you get into the game pre-lauch (beta's and early access stuff) then.. AFTER the game fully launches, they send you a second e-mail with the 'retail' key. BOTH of these keys 'should' also be listed in the 'game history/list' withen your account on Direct2Drive as well incase the emails either get lost, ate, or just dont show up.
