Cities & KnightsCATAN
There are three tracks, Science, Trade and Politics, each with 5 levels. To move up a track, discard the commodities shown for that level: the first level costs 1 commodity of the track's kind, and each further level costs 1 more. You must have at least 1 city on the board to buy an improvement.
