Land or water? Land if 2nd d% is less than the 1st d%, and use the lesser # for the amount, like I do with an age and gender roll for a random PC.

Do diagonals again?

Pick points to make a triangle.

Oops!

Another wasted Saturday night...

Ocean, shore, wetlands, grassland, forest, mountains, desert, seven terrain types. d% times seven, round up, 1 to 7. .59*7 is 4.13, round up to 5, forest. Each terrain tile is an up or down triangle, roll d% vs d%,  if the 2nd roll is less than the first, an up, northerly triangle, vs a down, southerly triangle. 1st is 51%, 2nd is 43%, up or northerly.

Diamond quad instead?

D% for size and type of terrain, type then size, two rolls?

Add mountains to forest and desert?
