Economy AI is just, well is there even one?... Starting the games usually with tech lvl4, the AI during the entire game has only/mostly build mines, farms and bio-fuel buildings in their zones(this game had plenty of rainfall so no water stuff this time which is nice). All of these are bare minimum to keep armies going, and I dont find any places with my spies etc where it would have buildings besides starting buildings for industrial capacity or BP! It does not really advance in technology at all during the game and easily falls behind as it has no BP production (and this is with nemesis and max difficulty). The AI really needs to know how to build its empire if it has zones that are not bordering hostiles, or at least give the hardest AI some free/cheat* points for building BP assets and factories.
*I would prefer if it would be done without "cheating", but I would rather take hotfix now than wait 6+months for something to change
AI nearly never upgrades troops (it still has units in uniform when it has new models with heavy combat armor available). AI nearly never uses air forces, still.
I keep returning to this game once now and then, its nice to see improvements but it also pains to see some sides of the game still have same issues

Always nice to see new content coming up, but hopefully you find the time and motivation to look at the old stuff too vic!
I know I only come whine and post bug reports, but its because I like the game
