The Yakuza games are a bit hard for me to explain or classify, but they certainly are unique. The Yakuza games themselves had a small audience for most of their existence, slowly getting more and more popular as time went on. As a result, the older games can be difficult to find. It is also why they stopped dubbing the games until they became more popular. The Yakuza games have a semi open-world structure. In the case of the first Yakuza and some others, it is part of a city. There are storyline missions and countless side quests. The combat is fun and you level different aspects of your character (In this case Kazuma Kiryu) that can improve your overall abilities and health using experience points you gain from side quests, story missions, encounters and even things like eating and drinking different things. The story is intriguing and has some mystery behind it. It was a lot of fun and a series worth getting into.
