I've never played a Yakuza game but wanted to play Like a Dragon and am about 6 hours in. I'm enjoying it so far. What I found the most interesting so far is one of the mini-games that I've never heard of before. I'm sure I've seen it before in several anime, I've just never paid close attention to what I was seeing. It came up in the game and I was too intimated by it to even try it. After I got through with my gaming session I looked it up on youtube just to find that it is a real game and not something that just exists in the video game.
It was Shogi. After watching some tutorials on how to play it, I'm now wanting to get my own board. I suck at classic chess but this seems so much more interesting and fun.
