I bought this new, and my child played with it. The case has some minor stains. My child really loves "Oshiri Tantei" (Butt Detective), and since they were old enough to play games, I bought this to try it out, and it was a huge hit. They were 4 years old at the time. They were absolutely thrilled! They could become Oshiri Tantei's assistant, walk around the town they saw on TV, and enter Lucky Cat. All the characters had the same voices as on TV. The original story was so interesting that it wouldn't feel out of place as a special episode of the TV series, and my child could understand it. I bought it at the regular price, and it was worth more than the price. As a game adaptation of Oshiri Tantei, it's a wonderfully made game, a model of its kind. However, the story is short overall. It's for children, so that's to be expected. I wish there was a sequel. And the recommended age range: 4 years old and up, under 6 years old (They rapidly lost interest at 6 and a half years old. In Oshiri Tantei itself.) The child should be able to read hiragana picture books on their own. It's good to have some prior experience with simple game controls on a Switch or something similar. Game difficulty: 4-year-olds will find it difficult without an adult's help. 5-year-olds can play and clear it on their own. 6-year-olds will find it not challenging enough. If you have a child who likes Oshiri Tantei, I think it's worth buying.
