map difficulty rating
we all know its easier to play in desert then it is in ice. desert would receive a rating of 1, while ice would be rated a 3. the consideration is the amount of water in the map most likely. the more dry spots a map seems to have, the higher the difficulty rating. a map such as the nile or tron would have a rating of 2. maybe even have the rating scale go up to 4 or 5, if we really wanted to go in depth with this.
