Alienware Arena, the member community for owners of clunky plastic PCs with gibberish written all over them, is giving away 2 copies of Dragon Age 2 in its monthly rewards point program.
The giveaway is done by users bidding their award points in the sweepstakes. You can earn points by creating an event, posting in the forums (so long as your threads don't get "nuked") and participating in community events, such as sweepstakes and online play events. There's about a day and a half left in this sweepstakes event, though it appears that only points earned prior to the sweepstakes period can be applied to this giveaway. Other prizes include 21.5" monitors and game time cards for World of Warcraft.
