In Nanu Planet, you play a pig-like alien explorer who, in the process of crash-landing on a strange planet, gets separated from your sweetie, whom you spend the game trying to find.
The planet, like Korea, is divided into two hostile countries, with a demilitarized zone between them; you land in the DMZ. Theoretically, the game is teaching you something about the history and current state of Korea's division (the game was funded by a Korean government agency and Samsung); however, the connection to the real world is fairly notional, and it's best considered as a charming, if somewhat awkward, graphic adventure.
