I don't know the exact conversion rate with yen, but about 40$ for one of these with only four games.... It's kind of laughable compared to something like the NES Classic, which has 30 games and retails for 60$. It's definitely overpriced but it seems like a fun novelty, and it almost seems like it's purpose is to be a novelty. If it outputs to TV, or the screen magnifier it comes with actually works, it would make for a fun little handheld. This clearly seems like it's supposed to cater to Japanese audiences and I don't see them coming to the US unless if the lineups change for some, especially the yellow model.
