Not really mega just me typing down ideas while I get more workers, and I'm gonna split this up into the super important categories
it's bad. really bad. It requires a 40x40 area to support two transfer nodes. There should be a much better software generation facility that still keeps true to insectoids.
Atmosphere- Zolargs have no way to remove large amounts of atmosphere, especially if they are on a sugar or water world. The crystal vaporizer on lava and ice remove a bit, but you need regions of them to keep up with growing cities.
Policies- Zolarg barely have any governmental policies, which make colonial management more difficult, as well as charter management, the deluxe command should have all the policies of the high-level human government buildings
Unholy Uranium gen- this building has always been overshadowed by the core mine, if the unholy gen had a buff it would see a lot more use
Petroplant- Has an extremely niche use, zolarg colonies have no reason to remain a charter and so this plant is almost useless, pair that with the extreme difficulty of producing oil without unholy core mines makes even dependant colonies petrol plants less useful than wood spires. If this building produced much more power it would be a very viable option
Ships- probably the biggest one on this list, zolargs have no option to store ships, meaning that ships are largely overshadowed by the hall of ancients money-wise, a dedicated starship storage site or a buff to the current storage would make starships able to produce much more money
obelisk of plenty- with the introduction of the improved hall of elders and the online communication buildings, both this structure's strongpoints are now its weak points, this structure definitely needs a buff if it's ever going to be viable again.
Obsidian burner- falls into the same category as the uranium generator, doesn't generate near enough to be viable versus a core mine. Combine with the fact it produces as much atmosphere as a paste burner this can smog up your colony extremely quickly if this is your main source of obsidian. A buff to output or the ability to make it without antaura is needed for this to become useful
Aluminum roads- they are too white, on ice worlds, you cannot see them
this is basically my two cents on some of the balance issues in insectoids. I don't really provide much of a solution to any of these issues, but at the very least I put the issues out there, and maybe someone more creative can think up a solution. I'm looking forward to ideas in the replies :)
Lava worlds- when these first came out obsidian was rare and expensive, especially when races started being able to use it. Now every race can produce it extremely well, and the price is nothing compared to its old price, combine this with lava worlds high difficulty and lava worlds are almost never used aside from something to shake it up a bit. Id like to see the challenge of a lava world be more rewarding to make up for losing 20% of your colony every so often.
A good way to do this would possibly be able to stop the eruptions on the lava world with a very high research tech, possibly utilizing many starships in order to achieve it
