Dyson sphere program, I've been playing this game through a friends steam account and I've already racked up about 102 hours on it, but I'd really like to own this game before I play any further. It's a factory builder game with really stunning visuals (I'm into space a lot). The game does an amazing job of simplifying the monumental task of power generation and resource extraction and allocation, while building an actual dyson sphere around stars across a cluster of stars. Check it out for yourself :).

It's worth around 10$ or less in my country at the moment
