I have worked through some of the more annoying planet generation bugs and landed on something that looks like this. This crusty plant has a low laying sea in the north and normal ice cap in the bottom. One large ocean and some smaller land locked ones with some significant mountain ranges I'm sure are filled with mineral deposits.
I wonder if Planet 182781 will ever appear in your galaxy? More than 4 billion planets are possible with this algorithm.
Anyway, I'm happy for the moment with the planets that are generated. They are enough for the next phase of the game, which is surface building.
I decided that I wasn't going to have players build on life size planets in the BETA version of the game.
