All I can say is, you obviously haven't been playing these games.
Have a look at my gamer tag if you must and you see that I've played Yakuza IV, I've also played the 1st Kezan on the PS3 , Yakuza III (Both of which I can't prove but never mind) and still own Yakuza Dead souls on my PS3 and Yakuza I and II on my PS2 . Yakuza 5... well I've only played the demo and while it looked nice its not the most amazing tech and as for Ishin I only played the demo on my PS4 but the tech is nothing new and no way is it fitting of a SEGA Japan next gen game
So don't come at me on that one, thanks
From 3 to 4, the number of protagonists quadrupled and with them came new fighting styles.
Its much the same game with the same animation patterns, much the same gameplay and adding in the odd new style and move is a very basic thing . Yakuza IV suffers from much of Yakuza III issues with not just the graphics but its out dated battle system and the map system is outdated (not be able to mark your next destination and so on ) .
but its like there's no lighting at all or no designated light source
Yep and the water effects are basic and poor too . Yakuza looks amazing in the cut scenes but suffers when in-game
Look at BINARY DOMAIN that uses the exact same engine as YAKUZA and that game had brilliant effects and was up there with the best third person shooters at the time.
That's over 2 years ago and in 2012 . The world moved on now . Binary Domain was the last game I played that displayed the old SEGA magic . The tech was brilliant, the AI amazing for a Japanese title and SEGA Japan put its own spin on a established genre and used plenty of western film references
In short classic SEGA Japan and sadly one that's not what it once was
DEEP FEAR another game surpassed Resident EVIL but because it was on a hardware deemed less powerful it was dismissed when the facts are that the Saturn was a more powerful system than the PSX.
Deep Fear in no way features better GFX than Resident Evil 2 . It looks great for sure (and sounds better) but the main characters models aren't quite as good and there far more enemy characters on screen at the same time in RE 2
That's like saying that tekken was a better title than VF 1 and 2 when the board used in that was way more powerful even the saturn version.
Tekken 1 did look better than VF , but VF 2 on the Saturn kills Tekken 2 .
Even the RE saturn game shows that when you go into the specifics of the procesing power and the detail of graphics of that game compared to the PSX version.
RE looks worse on the Saturn for the 3D graphics : The characters aren't as smooth and the Saturn suffers with the transparent effects too
Also YAKUZA had the use of the Magical V engine to map faces and real expressions onto it. Something that Tecmo licensed from sega and used for Ninja Gaiden 2.
That's just for the cut scenes and facial mapping lol not that Ninja Gaiden 2 won many pundits for its graphics in the 1st place,but thats a different matter . I don't think anybody has any issues with Yakuza cut scenes. And well even SEGA magical engine as been suppased by the tech used in 2K or Ubi games now
