Another year, another Call of Duty. For some gamers, it's just business as usual: they'll buy the next one because all of their friends on Xbox Live are buying it, and they might complain about problems with the latest year's entry while wishing for the old days, but they'd never consider not buying the next one. Why? See above: it's because all of their friends on Xbox Live are buying it. For those of us hardcore, PC-oriented, enthusiast gamers, that seems silly and completely insane - but it's actually what most gamers are more likely to do.
