This is my analogy for the two games' campaigns, and should explain pretty clearly why I feel the way I do about them. 

Uncharted 2 is like a romantic passionate night of love making. It has pacing, and build-up, and incredible climaxes. It's a memorable, satisfying, and fulfilling experience that will stick with you for years to come.

Modern Warfare 2 is like jumping right in, blowing your load, and passing out. Yeah, it was fun. It also was extremely shallow, had no build-up, and wasn't particularly special. It was nothing but a wild ride without any pacing or development to give it substance.

Of course, sex is always awesome, but while one experience will be a treasured one for many years, another is simply a passing pleasure, without depth, pacing, or development. 

Now this is a metaphor I can understand

Good god did I lol. That was the best thing I've seen all day.

Yeah right >.>

You wouldn't know passion if it crawled up your butt, died, and blamed Wii Music.

LOL.

Nice summary.

MW2 = God of war = Gears of war = GTA = assassin creed 2

= PORN GAME

In short, Uncharted 2 would be your wife, while Modern Warfare 2 would be your mistress.

Wait what?

Couldn't agree more.

Excellent thread.

Uncharted 2 Baby!

Yeah, they're like sex because I always talk about them but I only get them once or twice a year.

Replace Uncharted 2 with Assassin's Creed 2 and Modern Warfare 2 with Uncharted 2.

That's how I feel about AC2 and UC2.
