While Angry Birds is a good game, found it to easily dominated. Plus, you have to pay for the full game... as far as I'm aware, Crimson, (except Ch. 3) is being offered for free in all its glory (For this last weekend only.) Angry Birds just gave you a short 3-5 level demo of its product which would entice you to purchase the whole thing.... If Bungie would to offer the full game for free (including Ch.3), then it may be possible for the Steam Pirates to go out and make some fried chicken and pork chops.
