Is there a way to make the planet selection not be random but be the same each time you create a game? I'm specifically talking about AI games.. but the concept could apply to any kind of match. Usually a random planet gets chosen.. Maybe a way to make it always default to the last planet played on? or let you make a deck of planets that are your favorites and randomly pick from them?
Instant sandbox has a lobby mode that lets you open a preconfigured lobby. I think you'd have to disable local server to make a public game, and it assumes most slots will be AI. It's unable to create titans games at the moment, but I hope to start working on that any moment now.
