Did you even watch the trailer? There is no change between the non-player sections.
Yeah I have and even in the terrible quality video, there's a downgrade in graphics on things like the jackets and so on. Hey look loads of games do it (Halo V, Tomb Raider, AC and so on) unlike Shenmue where they was hardly any downgrade at all
but Yakuza 6 isn't the massive leap the team could really do if they were given 2 to 3 years to work on the game . This gen it's really hard to make a bad looking game.
And to me the big jump with Yakuza was Part II (which must have pushed the PS2 to it's limits) and Yakuza 5 .
The whole thing is a massive leap from Yak 3,4,5.
It's a leap, but there so was Yakuza 3 over part II. It's to be expected given its new hardware . I really doubt its a new engine though and just building on what's gone on before,. When you just have 1 year to make a game with the same team. You're not going to see huge engine leaps and the AI seems really really dull in this demo too and the added characters just there for the sake of it
I like new locations too but moving the series out of Japan makes no sense to me at all..
Just because its Yakuza doesn't mean it got to take part just in Japan . Black Rain didn't need to be filmed and just take part in Japan. The Japanese mafia like the Italian mafia operate in places like America
EDIT: I forgot to mention that the director for this is the director of Yakuza 1 (and F-Zero GX
Ueda-san was the director for the 1st Yakuza games
