perfect run. i owned all russia up to berlin, all china, all the arabic speaking countries fused into a single one. all three producing 0 unrest and a lot of money. mars was all mine (quite literally) extracting enough for every need, all my bases had 4-5 layered defenses and marines which meant they couldn't be taken.
i had to take china from servants's hands, while they just went and took it i had to bring pop support to 75 and unrest to 7 to have my max stat guy have a 26% crackdown chance. i savescummed like crazy.
then they couped the european union out of the blue. 0 unrest, 0 support. couped.
then they infiltrated the usa just like that.
they also turned india in a pinch. when i had tried to, my max stat guys converted a grand amount of 0% on a success and 1% on a crit.
then they gifted india to aliens. game over.
this is retarded.
Your post (and your other posts in this thread about the AI magically fucking you over) sounds either like bullshit or like you're doing something horribly wrong and are painfully unaware (like going massively over your CP limit or some such).
I think it might be the latter as if you claim that "Mars was all yours", you're doing it wrong. There's no reason for you to waste MC points on controlling ALL the bases on mars. You want to control the best resource loads. Less profitable base sites, you just make sure it's not fe. the Servants who control them (if you play an anti-alien faction obv). If they do, you either obliterate these bases or capture them and sell them to factions that are more aligned with you - so that you're not wasting precious mission control points on bases that really don't bring you that much benefit.
At some point even this has diminishing returns as the pro-alien faction (def the servants, not sure about the protectorate) starts receiving "subsidies" from their alien overlords, meaning that you cannot indefinitely cockblock them from going into space.
For each of your suboptimal bases on Mars with poor resources you could have a base on an asteroid, Ceres, Mercury or whatevs with greater yields, or an orbital with great boosts to your research, or a bunch of other things.
EDIT: Also, 4-5 layered defenses + marines on EVERY base? This isn't a game where you turtle and build like this. This game isn't about map painting. This is more of an AI War kind of a setup, where for half of the game you try to do your thing without pissing the aliens off too much and then start very rapidly arming up and going into oen conflict once you're ready for it. And you carefully define which stuff you own are absolutely critical and which are ones you can sacrifice, because you WILL give ground to the aliens and there's no possible way to build up your entire empire to be completely impenetrable. Most of these defenses could have been productive modules that give you boosts/resources rather than eat into your resources.
If you have so many defenses on ALL your bases (which you also apparently set up super inefficiently if you're trying to control ENTIRETY of Mars), you really need to understand the game a bit better and git gud. I'm not an expert at TI and I'm learning the game just like everyone else but there's definitely a lot of problems with the way you're playing.
