I'd like to explore the reactor concept but as the main gameplay mechanic. But this may happen as a prototype, after Tea For God.
It's quite possible that all the menus will be gone and if required, replaced by in-world solutions. I liked the menus as it reminded me a bit of some quite old games (like Magnetron) but the more I play TFG, the more I realise that they just break the pace and immersion.
