Virtua Quest was called the real Shenmue??
When did this ever happen? I never heard of that
Yakuza being called better than Shenmue in general has been said for years so you dont really need to even specify Shenmue 3. Many Yakuza fans feel Yakuza is the 'proper replacement for Shenmue' and all that noise, even though they are different games despite Yakuza obviously taking some forms of inspiration from it. Yakuza's DNA is beat em up (hence all the random battles, etc). Shenmue's is more point and click adventure (hence all the detective solving/talking to NPCs, investigating for clues etc)
Both series have their strengths and weaknesses. I dont like saying 'this is better than that'. It doesnt feel right to me. If Yakuza is the arms, then Shenmue is the legs. Why would you cut off your own legs?
In any case, you can't really make a judgement call on the Yakuza series by only playing Yakuza 1. That isn't even remotely fair. Yakuza 1 had a bad dub (good actors, just horribly directed with a botched script), fixed camera angles, and many other shortcuts.
The game was remade into Yakuza Kiwami which is much better. Same with Yakuza 2 (Yakuza Kiwami 2)
When the series moved to HD with Yakuza Kenzan!, a historical what if period piece spinoff, is when the series got an overhaul of sorts; free camera, completely 3D rendered environments etc. Thiis was repeated in Yakuza 3, then on and so forth through to Yakuza 6. The story focused primarily on Kiryu, the series protagonist, who in Yakuza 1, started off as a 35 year old ex convict, and his adopted daughter Haruka, who started off around 8 or 9 years old in Yakuza 1, and by Yakuza 6, she was 20 years old and Kiryu was 48. Each Yakuza game took place in the actual year and month the game came out in Japan (aside from Yakuza Zero, which is a prequel set in 1988 when Kiryu was 20 years old). No other video game series did something like this so its pretty special in that regard. You got to see the character development of these two main characters and how they grew over the years from 2005 to 2016.
Now Yakuza 7 is coming out, which stars a new protagonist, and the gameplay has gone to turn based, so that right there is a huge change.
I never thought it made sense to pit Yakuza and Shenmue against each other. Same with Sleeping Dogs. To me, if you're a fan of one, you should be a fan of all three. They are all special in their own way. Some people just like to be fanboys I guess.
