In real life, asteroids are not big enough to have enough gravity to hold atmosphere for very long. To simulate this, i would make it so that on asteroid map, atmosphere is slowly reduced over time, and the player has to make up for the loss in order to keep the asteroid at optimal atmosphere level. It would be a balancing act, but it would pose a unique challege for this particular planet.
In fact, I think that each planet should have a unique obstacle to overcome aside from the usually lack of a certain resource, just like the lava world has a specific challenge to overcome aside from the lack of certain resources. Red planet should stay as is though, since it's supposed to be an easy, stable planet that beginners can learn to play on. Every other planet should have at least something wrong with the environment that needs to be resolved before the colony can progress much further.
I'll keep adding ideas for more environmental challenges on other planets in this thread.
Her are my ideas for other planet types:
1.) lunar word: Meteors bombard the surface at a slow rate as long as the atmosphere is under 2.5 mil. small shelters, green houses, solar panels(not towers), ore compactors, and h3/water extractors are obliterated on impact, while all other buildings sustain varied damage but are not destroyed on impact unless integrity of structure = 0% after impact.
2.) Forest and sugarland map: I'm still thinking about this one, but it might work with a few minor tweaks. Monsoons could rain down on the colony, creating water pools on certain areas and drowning any colonists caught in the pool and doing the same for workers/rovers. the pools wouldn't form over buildings, walls, or paths, so putting paths allthroughout your colony and putting walls around to ensure the safety of your colonists would ensure a measure of stability. But there would be a second factor to the monsoons, lightning. If lightning were to strike one of your buildings, it would cause devastating damage and may even destroy smaller buildings on impact. The only way to prevent this is to build lightning rods that attract the lightning, but even those will degrade pretty fast over time, so you would have to be careful of how long it's been since you checked each rod, and each rod would only shield a limited area/radius. You could implement more advanced rods to cover more of an area and last longer The plus side is that when water pools are created, water can be gathered from them, and lightning rods would generate a certain amount of power for a certain amount of time after being struck. To make it more interesting, you could make forst and sugarland planet types have maybe 20-30 mil atmosphere and make the monsoons stop when you reduce the atmosphere to below 15 mil.
Ice world: The ice world should have a freezing affect on colonists/ both human and xolarg, since its supposed to be super cold I would imagine. Adding a thermal energy resource, not as a terraforming factor, but as a requirement for colonist survival, would be a great addition to the ice would and wouldn't be a tradable resource. You could also implement snow storms that damage structures and make colonists require more t-eng for the duration.
Abondoned world: This planet could also be a monsoon world, but having monsoons on all three earth-like worlds would be too much monsoonage. I'm still thinking about this one, but I'll get back with yall when I come up with something. In the mean time, please share your ideas for environmental effects for each planet in this thread. Remember, we want at least one world that has nothing environmentally wrong with it except the fact that there's no atmosphere, so no ideas on red planet.
Really? No one was interested in this one? At least vote when you look at a thread with a poll
it can be add in a option "more difficulty" like:
"normal" "more difficult" "imposible" "nightmare" "are you crazy?" "instant dead"
and add a succes if you build a particularity building in "nightmare" "are you crazy?" "instant dead"
and if you succes to build star gate/have a population to 1 000 000 you have the premium free or something like a small badge in the game
