Aliens vs. Predator

Now guys this is a different sort of post; I want you guys to tell me if AVP for the 360 is worth the money and if it should be a part of the Revive Defib list. I've been meaning to get it for myself but recently second thoughts have crossed my mind and the purchase has been blown off for months now, state your cases!

Well I own AvP. And Ill tell you right now, its a great game with many issues. Nearly noone plays it anymore because everyone is waiting for Aliens Colonial Marines. If you can get it for 20 or less, I say go for it and Ill play with ya. If its over 20, I say no
