Well first of all am gonna make it clear that i don't own call of duty black ops as yet i only have mw2 but base on my online experience with mw2 on the ps3 is that i hardley see any log with it don't get me wrong it logged but not that often and it will logged base on the strength of your internet.Anyway what i wanna talk about is the comparrison between the two and i watch alot of gameplays on youtube and videos of gameplay from a friends on black ops they say that the story line is one of the best story line of all time for the call of duty series but i heard that it logged alot online i dont't know if it's because of internet signal strength but i heard alot of complain about it so i wanna know whats your comparison between the two.
