Yakuza was a little different than I thought it would be, but it turned out to be pretty fun. You basically run around, beating people up. Okay yeah, sometimes you help people find their briefcases and buy art, but mostly you just DESTROY!
The camera doesn't always go where you want it, but you can press L2 to face it the correct way. Sometimes the movement control seems a bit wonky as well, but you get used to it. During fights it can be a real pain though.
Aside from the movement issue, fighting is quite fun! For the first few chapters it only seems like you need to use one combo move over and over, but after a while you get more powerful enemies that require a little more strategy. This game actually makes you use dodge! You can't win some fights without it. I never, ever use dodge in games so it was kind of refreshing. And you can pick up almost anything off of the ground and use it as a weapon. Hitting someone with a table is pretty satisfying, let me tell you.
The one major flaw is the language, not just because the English dubs are terrible, because they are, but the swearing is so ridiculous that after a point it just becomes funny. There was a cut scene with some street gangsters that literally had at the very least, 2 swear words per sentence. I'm all for realism, but it was so over the top. Nonetheless, if you can ignore it, and even embrace it, this is a fun game.
On one final note, I'd just like to say, this is nothing like Shenmue whatsoever, except for the fact that you're a Japanese dude walking around town. Seriously, the similarities end there.
