Latitude

About Latitude, from BoardGameGeek:

Work with other players to create a map of the realm, but only the most accurate player will take the glory. Latitude takes place on a blank map which slowly develops as the game goes. Each turn a player places a land tile (sea, plains or mountain), and places a marker showing how big they believe that region will be when the map is completed. Each region is a contiguous group of the same land type, and regions cannot have the same value marker repeated. This leads to high level strategy, as region get completed, blocked off and more, all in a simple to play game with clean efficient rules and beautiful original non-AI artwork. -description from the publisher
