With a perfect mix of fun and brutal combat, exploration, storyline, action-RPG levelling up, variety and great length, this is kind of the ideal game.
Honestly, there is so much content in this game, it's astounding. The authentic Japanese voice acting is great (with English subtitles), the graphics are slick, and the many cutscenes which progress the story are beautifully animated. Wouldn't change a thing.
Not many action titles are as polished and well-rounded as Yakuza 4. Basically, if you've ever liked an action game, or just want a game that will keep you entertained for ages, you'll love this game. I know I do.
It's also ideal for newcomers to the Yakuza series, as you can watch lengthy summary cutscenes of the Yakuza 1–3 game events, meaning you won't have missed a beat.
