Since there's only a few work days left before the official release, I'd really like to point out a couple of the few remaining major issue I think there is with the game. These ones in particular because I think they're going to potentially cause a lot of problems with the influx of new players that's going to happen on the official release.
Firstly is that the listed difficulties for the asteroids is often very far off from the actual difficulties. I've got a full thread discussing that stuff here:
While an alternative fix is to adjust the difficulties of the starts to make them match up with their intended orders, there might not be time for that before release now. So the difficulty order of the different starts relative to one another at the moment should be:
Terra and Oceania (easiest)
Verdante and Rime
... (large difficulty gap)
Aridio and The Badlands
Secondly is how crippling the lack of gold is on The Badlands and Arboria in the late game (unless you get a gold volcano or a world trait that gives gold like geodes). In fact, the bulk of the difficulty of those starts is mainly from you not having any gold on the map. Without it you cannot use the oxylite refinery and are forced to ranch Pufts (which must be acquired from care packages on those maps) in order to fly petroleum rockets and use rocket boosters. This drastically restricts rocketry and forces the player to just run steam rockets back and forth to the initial destinations until they can jump straight to liquid oxygen. Afterwards, they cannot make super coolant at all unless they get a destination with gold. Either adding some special source of gold for those maps or an alternative method of producing it from the oxylite refineries would be the quickest and dirtiest fix until there's time to implement a better solution. Side note, this would lower the difficulty of Arboria and The Badlands if this were implemented. The relative order would be the same, except that Aridio would be harder than The Badlands rather than being roughly on par.
