yes it can, because it takes the piss, almost all of the games today take themselves and their story way too seriously.
subject matter almost always has to be dark or brooding, flavor of the week enemies based on terrorist organization x, y or z or what ever else.
yes some games incorporate humor, but to be perfectly honest 8 out of every 10 shooters is almost always "serious business" and almost no fun.
not that it's bad, just tiring really
