Satellite Reign is amazing, but it was released prematurely. The optimization is horrible such that you'll often struggle to hit 60FPS even on modern hardware, let alone what it must have run like when it was new, some achievements are broken, and there's bugs abounds - like getting stuck in geometry. There's some fan mods that tried to fix stuff but I think these sort of things really push people away. The entire concept of how the game works is also not well explained in the tutorial.

I'd still rate the game a 7/10 because it's so absurdly fun if you can get passed all of this, but it's easy to see how it probably never reached even a fraction of its potential market.
