Side note, I remember reading an article a few months back that suggested our sun is an uncommonly stable specimen of its stellar class, emitting far fewer flares than what models would assume it to, rather than a typical one. I don't think you can really convey all these orders of magnitude in a typical 4X game though, and if you tried, you'd end up making the game into more like Cookie Clicker.Ĭlick to expand.You'd also need something like a moon's worth of dumb/metalic mass to replace them whenever the sun farts out a solar flare and cooks several arcs worth of satellites + the energy to clean that slag up (assuming that trillions of satellites shotgunning out of their orbits don't cause Kessler syndrome or shower the rest of a systems infrastructure in fragments) + any collector electronics (the satellites may be dumb mirrors, in an orbit held in place by gravity and solar wind pressure, but you do still need some logic to orient them properly and beam or focus that power to solar collectors or a battery-moon, somewhere. if you want to build a really big computer without too much ping between opposite corners of the computer.

If you had already colonized a large part of a galaxy, the only advantage a Dyson sphere would give compared to just making the same amount of solar panels over numerous stars (and thus having fewer constraints on locally available material) is that the Dyson sphere concentrates a lot of usable energy in one place, e.g. It's not necessarily a lot of energy from the perspective of some galactic-scale entity, since galaxies have billions of stars and other stuff (our galaxy is estimated at around a trillion solar masses). You then have to consider the amount of material involved in building it, which may be a challenge even if you can rearrange all the matter in the star system (since most of it is hydrogen/helium, only a small amount is good building materials like carbon, iron and silicon). It doesn't do anything especially clever, it's basically just a huge array of solar panels. I think the point of the Dyson sphere as a concept (in general, not specifically the Stellaris implementation) is more of a thought experiment to understand the immensity of even a single medium-sized star compared to anything we have harnessed up to this point on Earth.
