The trade in price for Blops2 has plummeted, one person being offered £15, another offered £25. Apparently they have a glut of traded in Blops 2 games so have cut the price. I really can't say I'm surprised at this as so many people have issues with the game. Me, well I'm hanging on to it in the vain hope that they fix the problems, however I won't be buying and DLC until they do. It's strange as I got £30 for Dishonoured after owning it for 5 weeks
Anyway I have every COD since COD 2, I quite enjoy going back to them and can still find an online game at any time.
On another point I've heard that some people are reporting players to MS enforcement (due to the large lag difference) in the hope they will force a fix. I can see the point but this needs to be freed up for genuine cheat reporting not because they are frustrated with Treyarch. Why not put pen to paper and write an old fashioned letter to Activision and express your anger to them, you never know if enough do it they might actually do something.
