@kool_kat,
As someone who spend almost 1000 (!) hours in this game and also being an active modder I first want to say that I'm really disspointed that the game didn't grasp you from the very beginning.
At the same time I can imagine what you write, since my very first experience with the game was the same.
I want to comment on a few points you make since they are simply not correct and it would look unfair imo for the developer and other players who want to try the game.
Unit models:
You can set the unit size in game options. Default is medium size. Some like them bigger and some like them smaller. You can all set this in game and it's the only game I know of where you can change the 3D model size ingame.
(with modding you can even make them miniscule if you prefer). This is all done because players have different preferences.
See at a glance:
You clearly did not read any FAQ, manual, review or dev diary and even not went to game settings. There are around 50 ingame settings you can tweak from saturation of terrain, color overlay, borders, transparency, 2d /3d map etc etc etc
It's impossible to say with all this customization that you cannot find a way that works for you. All sliders can be set from 1 to 100 %
You probably did not even see the buttons below the minimap. most of this visiblity changes you can simply change with a single mouse click.
I don't say it's wrong you did not find out. You play and you are dissapointed, I respect that, the game probably fails for you to make all options clear.
Just yesterday there was a 1.5 hour during Developer Stream on Twitch about customization ONLY:

Audio
Personal taste. I have many from the over 100 tracks I like to listen to still after 800 hours. Not all of them of course.
Customization
I play games since Civilization 1, Dominions 1 and Homm 1 and I did not encountered a more flexible engine then Aggressors has.
Even the customized maps (which is not even a main feature of the game) offers many different terrain shapes, you can set again many parameters with enemy distribution, size of map, amount of enemies and many, MANY more starting tweaks, normally ingame without modding.
Opening the ag file in any XML editor makes you expand the map size, map distibtion/continent ditribution etc even more. The possibilities are endless. I just released a mod myself with 10.000 (!) tiles and 48 factions. I was never able to do that so flexible in any CIV game and I'm not even an experienced modder, just a fan of the game.
Lack of completeness compared to Civ???
This one I simply cannot agree with in any way. Civ is a great series, I love them, they are my second most played games, so I know what I speak about.
In Aggressors ALL ingame features and mechanism works together in one single META. Resources, technologies, units, terrain, state decisions, objectives and diplomacy and trade are not MINI games inside Aggressors, they all make sense and they all have at least 3 strategical layers beneath them.
For example: Building a goldmine, gold is need, it not only produce, it also consumes, it have an owner, a territory and a faction, it has a road to it or a river, it has a city in range of it or not.......it's sooooo detailed. Really and that is just a single gold mine. Units consist of multiple parameters, from loyality, supply, morale, fighting stats and many abilities you can only achieve in fights or some you can train in cities.
All of these mechanism together makes that Aggressors is not using unit stacking and the AI is using the same rules as the player. I cannot say that their behavior is exactly like a human player, but at least they USE THE SAME RULES as a human player and making the game more difficult (again with many sliders at start) is not making the AI cheat better, but simply make use of a broader range of options.
Last but not least since you mention a 20 / 30 year ongoing game that reach number VI in their series with countless of DLC and a millions number of players with a new studio making their first strategy game. It's honorable you do, but it's totally unfair to compare them in my opinion.
This game can get much better! By the dev team (consist of only a few people and only 1 main developer) and by players.
I think you made a mistake. Maybe my post looks aggressive and angry. It is a bit. It is not personal (I don't know you), but it is because probably the game fails to get you attracted the first hour or two you play (I don't think it can be more).
This is a gem. A very detailed, highly complex, very flexible and VERY ADVANCED 4 x game, not a Civ clone.
I really hope you will review all the options you mentioned are not ingame once and give it another try another time. Really you will not regret.
Thank you for reading.
