Remember Gift of the Yeti, that holiday-themed Facebook game BioWare released earlier in the week? Apparently there's some material incentive to playing it.

Anyone who plays the free game will get a $10 discount on Dragon Age: Origins. The discount can be redeemed only through EA Store. You have to live in the US or Canada to be eligible.

If you're looking for a less selfish reason to play Yeti during work, how about this: it actually earns money for the Child's Play charity for children's hospitals. Every time the game is played, BioWare will donate a minimum of a cent to the charity. They plan to donate up to $10,000 in total.
