Dynasty Warriors 6

I picked up Dynasty Warriors 6 last night and played it for a few hours.

The Good
It's Dynasty Warriors
Graphics marginally improved
Fewer enemies popping in directly behind you
Skill trees
No bodyguards (they don't run off and get themselves killed)
Bows - Sun Shang Xiang, for example

The Bad
It's Dynasty Warriors
2-button button mashing reduced to 1-button button mashing
Why are enemies still popping in? Did you learn nothing, Koei?
"All new engine" apparently means "slight improvement on previous engine"
Cut scenes look like PS2 graphics
No bodyguards (to distract the enemy heros)
Voice acting is terrible, but this is typical

The Inexcusable
No online co-op. Seriously, not that hard. XBLA games have online co-op for crying out loud.

Final Assessment
I'll get my money's worth out of this game, since I enjoy Dynasty Warriors, but I still think Dynasty Warriors 3 (or was it 4?) was better overall.

Updated 2/26: added a few additional points
