It's out, huh?
I know some people who have long been awaiting the release, I hope it meets their expectations.
Personally I always find CoD's a good bit of casual fun, best not taken seriously if you have a keen eye for detail, scripting and definite progression.
A lot of the time, how much more can they do with a MP at this stage? They could scrap it altogether, going by the line that "everyone says it is the same all over again", but that would take away the CoD essence. :P
Depending on how frequent (and "new") their future games under the same series are going to be they should consider a way of linking up the MPs if they have the tendency to be almost duplicated. Regular updates to the system would not hurt.
