7. The Multiplayer
Let's be perfectly honest here, any Call of Duty title lives and dies on its multiplayer portion, and millions of gamers will log millions of hours in the online multiplayer arenas long after the solo campaign loses its appeal, and even beyond the arrival of the next Call of Duty title. So it's not a small consideration by any means. In the hands of Treyarch, we can fully expect some new engaging arenas to play in, designed not only to entertain and do their jobs during the solo campaign, but which will also offer rich environments for online play long after the veterans have learned every single nook and cranny of the levels.

But it's hard to be anything but impressed with this.
