I have an idea for a gamemode!
You’re a nucelar scientist who is going to build a nucelar reactor for City 17.
You can buy upgrades, like different reactors, nucelar fuels with different enrichments, better neutron moderators etc…
You produce power witch people in City 17 buys. For example a basic reactor produces 400 MW, witch would sell for 900 credits every 5 minutes or so.
