Speaking mainly on the single player campaign, this is a really good game, though it felt short.

While not as good as Cod4 (the best in the series) MW2 ups the ante and has absolutely wild set pieces and missions. It has a lot of memorable moments and is just a blast.

Though I will say, it is not as varied in game play as Cod4 is, it's a lot more consistent with just chaotic gunfights throughout the whole thing. But that's fine, this game makes you feel like you're at worlds end, it wouldn't be fitting to do different segments like Cod4 does.

This one just felt really fast, like much faster than Cod4 or WaW, this one blew by, which is fine as everything here is really good.

Definitely worth playing.
