LOWER THE PRICE OF THE RETAIL GAME
Make the game $50, $40 or lower. I guarantee people will feel more incentive to purchase the game with all the mixed user reviews out there influencing their decision. I only got the game because I watched videos on Machinima Respawn, and found that the game appealed to me. I am also a COD player, which sparked my interest in ONLINE fps shooters in the first place.
So...
Lower price leads to an increase in the sales of the game leads to more people playing online! Crytek should look into this soon because Modern Warfare 3 is coming out soon, and they will be screwed if they don't lower their price for Crysis 2.
By the way, I payed the full $60 for the Limited Edition retail version of the game; I WON'T feel cheated out of my money.
