The principal behind this project is that we want everyone to collectively work together to make an interesting, realistic map. We ask that all users follow the rules to ensure this happens, and so that everyone can enjoy the outcome of this experiment as it evolves.
Tiles are assigned psuedo-randomly. When you choose to add a tile, you'll be assigned a new, empty space based on criteria built into the system. Please try to work with what you've been given - if you don't like your spot, do not abort editing your tile just to get a new one - it goes against the spirit of the experiment.
Try to make your tiles make 'natural' sense. Try to imagine the way your tiles' landscape would behave.
Always base your tile off of what any existing neighbors have given you to work with. If a neighbor has a river that connects with one of your edges, continue the river into your tile. Avoid abrupt changes or unmatching terrain.
Try to make sure there is something unique and interesting about your tiles. It can be interesting to have huge areas of grass or ocean, but, these should be rare - dot some trees, or small islands in to break up too much monotony. Tiles of solid color with no details are not ideal.
Never draw letters, numbers, shapes, or symbols into your tiles.
