[Fathom Zero]

Excuse me, I realize now that the 4th one does. 5 doesn't, that's what I infer from the internet. And in comparison to the 3rd, 4th is a little bit of a downgrade. That's just my opinion.

And as for the Romance of The Three Kingdoms, I wasn't aware there was a copy of it for the X-Box. My bro owns the 8th one. I know the story. But we're talking about Dynasty Warriors. Dynasty Warriors doesn't have much in the way of story. If you want to flesh out the back story of the whole thing, by all means, buy RotTK, but it was specified to me that he wanted:

A) An X-Box game
and
B) A game with co-op that isn't too hard, but not too kiddie.

Dynasty Warriors 3 (and if you want, 4 or maybe 5) fulfills those parameters.
