This is definitely the most advanced shop sim that Kairosoft has released so far (at least on the American store). It has a lot of the features of past games, but expanded. You can now customize your stores, restaurants, hours of operation, and staff much more extensively. Many of the other systems we know from past games have been polished as well (such as using items to upgrade staff, going treasure hunting, researching, etc).
The only caveat is that there are a few small bits of text still in Japanese, but nothing that is in the main dialogue or that makes the game unintelligible. You really have to dig through the menus to find it. (For example, the default names for your managers are in English, but when you go to change them, the typed entry is in Japanese).
