I would like to see life support added into the main game, but the biggest problem is having it not be too complex. TAC LS is good, but it has a lot of resources to manage. I like the approach of USI LS because instead of having food, water, and oxygen, there is one resource, supplies (as well as mulch for waste and fertilizer for surviving). On one hand, I feel that some stock life support system should be added soon because there are so many life support mods for modders to deal with for supporting (Greenhouses). On the other hand, I feel that life support should come after the ability to use science to improve existing parts (which is likely to be a lot of work especially with balancing) because that would allow for recyclers to upgrade to near 100% efficiency.
