I see a lot of things missing for zolarg, although I'm still able to play the game to some extent. I feel like there are many resources that need alien or unholy versions. Below are some resources that I think need a better way to produce them:
Food: food is ridiculous, you need an entire small map full of the food fortification plants just to support 40-50k colonists over several maps. Humans can do much better as they have the tall farms that produce 500 food every couple of seconds, or the food processing factories that just spew out food.
water: just like food, you end up having to create an entire small map filled with these things in order to support your colony as it grows. Eventually, I'll end up needing another map full of them. This definitely needs to change. Humans can produce an overwhelming amount of water in end-game, even to the point of causing the atmosphere to plummet, why should zolarg be stuck with such an inferior water production
Ant paste: This one too, I have a map full of paste mixers and they still don't produce very much ant paste. Usually with basic resources like this you can usually get to the point where you produce more than you can use in just one small map, but these paste mixers are the devil in end-game.
Antanium: This one too depletes very fast even with a small map filled with them, but not nearly as fast an ant paste. Still, ant paste is for zolarg what steel is to humans, and we have a steel alien factory, so I think these should have an alien counterpart as well.
Aluminum: I think it would be nice if zolarg got their own unique alien aluminum gen that took antanium to generate aluminum. UCM's can churn out aluminum, if you build an entire medium map full of them that is. Who has time to build that many? And don't tell me that we can just build mines, because humans can generate everything automatically at end-game, and there's nothing they can't mass produce.
Wood: we're still stuck in the dark ages with wood, growing and cutting down mega trees like an idle champ I am. My idea in the "fleshing out zolarg" thread in the ideas forum mentions a building that can combine paste, cloth, and antaura to make wood. I personally don't care how much @basteklein
makes this thing produce as wood isn't too high in demand, we just need a way to automate that resource so we don't have to keep resorting to mega-trees.
housing: I feel like better housing is in order. The worship mounds do the trick but you have to spam them.
Colonists: We need a better way to get colonists faster. Perhaps in bigger housing, colonists could be produced quicker.
Importing/exporting: zolarg need the third and fourth tier customs centers. I recoomend the fourth being some sort of mystic gate that acts just like the stargate and consumes antaura. But zolarg really need to be able to export more than 1k resources at a time, especially if you're trying to prepare for a medium-map sized project and need several million of each resource and you have the money to import those resources.
Starships: We have the tech, but we don't have the means. This is the end of the game currently, and I feel like it should be more like the halfway point.
triantanium: I could've swore that zolarg were the first to get triantanium, yet I can't find any buildings for zolarg that produce it. I'd say that we should be able to produce it at some point. After all, zolarg invented antanium.
Charcoal,plastic,steel, robots, toys, paintings, brick, pottery, microchips, and instructions are all missing from zolarg. I feel like zolarg could use a lot of these in their own ways, but I also think that they shouldn't have access to everything that humans do, or else playing them would be just the same as playing humans in end-game. still, at least some of these resources would be useful.
I also feel like some of the resources in the game are lacking in ways to use them, so I just sell those to make money as I get them or gift them to my other colonies.
That's all I have for now, but I'm pretty sure I can come up with more if i think further about it. Those were the major areas anyway. i realize that zolarg are still under construction, so I understand why these aren't in the game, but I feel like zolarg has been put off for too long, and it may be one of the things that is causing the lack of interest from people of late. I recommend finishing them before doing anything extensive on reptilians side as people that have zolarg colonies have been waiting much longer than reptilian colonies have.
