I'd suggest increasing sell prices of invader stuff, at least. Also, I'd suggest making various special events (beast terror missions, graveyards, rifts, etc.) yield something you can sell for some money (currently the corpses aren't worth much at all), for example shai-huluds could be disassembled to produce expensive teeth or something. At the moment, these missions are money-wise worthless, yet take some time to complete (especially if you have village mazes, tough enemies, etc.; FWIW I also got glass spider once in antarctic and the mission was unsolvable: one of them was camouflaging on an inaccessible ice island, and I had to use debug mode to get rid of it)
I'm currently in January 2022 and total council funding is at 19M (I have the whole globe covered with 6 bases). There's still 3-4M surplus every month (with about 150 scientists). Yet I'm still only 19 % through the research tree. To make the game progression faster and reduce the grinding elements somewhat, I suppose you could also increase the council funding and how fast it grows. There could also be some items engineers could manufacture and you could sell, to make use of engineers and earn money, but I understand completely if you want to avoid that kind of economy (I have felt it's rather stupid myself).
Hmm? I wonder if these are phased properly. You are able to get X-contract likely much earlier than getting psions. It seems you get on the path leading to psionic powers through researching fire mage, rune mage, etc. I have postponed researching them to delay legionaires and more difficult enemies appearing.
But for what it's worth, X sniper rifles are at least very usable with humans. Others I haven't used that much (though rifle could be useful with spare clips).
BTW, I think the first alien base (hive) appeared in October 2021 or so. I don't think there's much chance of dealing with it yet, so I have had to leave it be and grow. Also, there have been some other enemies that seem to be non-defeatible for now (for example the UFOs with stalkers and the other beasts, the other ice thingies behind ice rift).
How for the love of god you have 19m from council? I barely scrap by selling most of the stuff since i cant keep more than 30 scientists in July of 2021 and i just got x weapons
