Its the console monkeys I tells ya! Fools the lot of them!
CoD lost me really when they started charging for PC DLC, whereas we always got it free, just some time after the consoles. At that point you knew it was ONLY about the money (its always about the money in some way...business is business, but its not meant to be ALL)...
for me it was to do with the map packs in a different way, it used to equate to 200msp per map but when that increased to 240msp per map i stopped buying them, especially when the mw2 1st map pack was such a big disappointment
