CoD games after COD4 are all similar enough that if you can play well on one of them, you can do the others quite good. With the exception of BO3 perhaps, because it actually added some more fun gameplay elements. (The running along walls / double jumping). But in general, the games are all quite similar. Then again, the days the COD games were actually good games are long gone (in my opinion). CoD2 remains my favourite by far, and CoD4 is a close second. Both of which are over a decade old now.
