I just got back so I have missed it apparently, but like you said never posted on vg chartz which doesn't surprise me.
The second demo has 4 different parts.
The first option in the main menu is some kind of geisha seduction mini game which I'm sure would make more sense if I knew what I was choosing in the convo options.
Second option leads to two different things, the first is a horse riding part which I hope there is a lot of in the game because it's quite good and not exactly easy. The second is some weird ancient Japanese game where you have the right buttons at the right time to win.
The 3rd option on the main menu leads you to 4 consecutive fights: 2 sword fights, 1 hand to hand and at the end a boss fight.
Yakuza's combat was already good but the swordfighting is even better. The boss fight was kinda lame, but it's good to see some timed button presses thrown in to make it more interesting.
Both demoes combined give you a pretty good amount of stuff from various, really different parts.
Thanks to Blacksaber for the sig!
