I've yet to smash open a Dyson Sphere in sci-fi RTS Sanctuary: Shattered Space, but I'm enjoying its take on Supreme Commander
Sanctuary: Shattered Space is a large-scale real-time strategy game inspired by Supreme Commander and Total Annihilation, where players can control up to 10,000 units. The game features a flow-based economy and combat centered around a Dyson Sphere, with factions warring on its exterior. A demo is available on Steam, and the full game is set to launch in August 2027.
