Using Hammer and Sickle as an icon for gathering. "hehehe ideology that killed 100 mio people le edgy hahah subversive clever" If you had used a swastika you would've at least shown balls, but I'm afraid you cut those off a long time ago.

The longer you play the more bugs appear and they start to cascade to the point you have to reload games, restart the game, sometimes saves get corrupted and you have to load further back, power starts to act wierd when you get over 1 million storage and 2000 generation and the display of the power, the ui starts to disappear, the AI breaks, Resources delivered from mining vehicles disappear. Worse thing is I have searched and scanned 1/3 of the map and not one above ground source of Rutile which has progress blocked me. Its a cool little game but damn it is buggy.
Not recommended Sep 10, 2026
Looking at the game, it seems interesting, but with no introductions to speak of, and no intentions to explain how stuff works, I don't feel like giving it any of my time.
Not recommended Aug 1, 2026
I don't like games that give you no idea what you're supposed to do. I spent more time outside the game looking at guides or watching videos.
Recommended Jun 10, 2026
For a game that one person developed by only themself, this is really impressive. It was a fine colony builder. The mechanics arent very complicated which can be seen as beneficial or not, but it was fine enough. Ive had some issues with playing longer multi hour sessions, but a quick reload fixed those. I had some problems finding the last blueprints for the achievement, but I managed to get them in the end. Overall a fine experience if you like a colony sim which in more chill.

Final Fantasy XI price: what you pay, then keep paying

The Final Fantasy XI price is two numbers, and the subscription is the one that matters. Our tracked low, what the Ultimate Collection includes, and when buying at list is correct.
