From Nintendo Now:
"Retro Game Challenge is a compilation of 8-bit games from the NES era. The thing is, you've never heard of these games, the reason being that all of them are original titles. Each game is heavily inspired by the games of the NES era--games like Galaga, Dragon Quest, and Ninja Gaiden. It is a pretty unique experience overall, as there is a lot of nostalgia packed into this game, especially if you were growing up in the 80s."
