Dynasty Warriors huh?

I'm looking to get a Dynasty Warriors game, but there are so many variations. Which version should I get on the PS2? Just 4 Empires, as it has all the stuff? It's confusing.

You should get the one that makes you the happiest.

Any Dynasty Warriors Empires game is a blast. Taking over territories is always fun.
