So I guess the question here is, what does AI war do that other games don't?
They allow you to fight tactically against a smart and scary opponent that's stronger than you, make decisions that matter and have thousands of ships to control when most games give you only dozens.
Maybe present it as a challenge. The focus is on beating the AI - they have rules made clear to the player, and the player has to abide by those rules and overcome the AI despite how strong and omnipresent they seem. They get a lot of scary defenses, but you get a ton of cool tools to try to overcome them with.
Every game is different - rather than having different resource locations, every single game is wildly different. Different AI, different planets, different random events, and so on.
I do think one thing AI War and many other games have had trouble with in the past is getting people into the game in a way that doesn't completely overwhelm them with choices. New players (and some people in general) don't like making decisions when they're somewhat uninformed, so giving players starting scenarios (and making them opt-out) can help a lot in giving players direction and experimentation. Telling people what the rules are, what's generally right, what's generally wrong and so on up-front is huge, and will give people like youtubers something to showcase.
