preferably an up to date one, i know from tweaking planets there are temperate 1-4 with two separate algorithms and different amounts of water.(biomes, not playfields you can make as many variants as you like by tweaking the parameters in the playfield. but the algorithms are preset.
That would be nice so I can use all the different algos in my sector generator tool - (just released for testing) https://www.dropbox.com/s/xk77v39zhotliea/Sector-Generator.zip?dl=0 would be nice to know all the working algos....
