It is rumored that Activision is planning on charging a fee for the multiplayer use of Call of Duty: Black Ops.
Not only will Treyarch and Activision loose sales but people will also protest any future games they do, I remember a interview Bobby Kotch or whatever the guys name is where he stated that he wanted to charge for online play but it would be next year and not this year.
The Interview he stated something along the lines that they would be charging $19 for 4 month's or $60 for a year on top of what Xbox live charges, he also said that future gaming addon's will raise in price to better suit Activision and the money they put into the games.
Now if this does happen I know a lot of people will return the game the very next day after they buy it and I for one would be one of those individual's.
No, i would get them charging PSN and online for the Wii sincere there online is free but Xbox 360's online is expensive enough.
