TL;DR:
Allow Biolabs on every planet except Gleba- If desired, this could be gated behind promethium science
Why?
- This maintains only 1 landing pad per planet as a logistic puzzle, and to keep GUIs simple FFF-417
- This maintains "it's cool to have a single location with lots of activity"
- This maintains "shipping spoilable Ag Science to another planet should be rewarded" 129833
- When megabasing, players now have up to 4 Landing Pads (one on each planet) to ram science packs through, alleviating the throughput issues we currently face trying to ram everything through a single landing pad on Nauvis 130388
- This encourages producing the 6 basic science packs on each planet, which is more interesting than only producing them on Nauvis
- Nauvis is still relevant as the only source of biter eggs and uranium, and Bioflux still has to be shipped to Nauvis
- If desired, the ability to place Biolabs on planets other than Nauvis could be gated behind promethium science
- Any lore excuse can be made. Maybe Biolabs are allergic to the spores on Gleba
