Blue Marble

A Korean knock-off of Monopoly. Instead of buying "streets," you're buying "cities" (Seoul replaces Boardwalk). If you visit your own city, you can build various buildings. Community Chest and Chance cards are conflated into one "Key" cards that give you either some sort of bonus or penalty. Other than that, it's pretty much identical to Monopoly: roll, move, buy land, or pay rent if someone already owns it. The player with the most money wins.
