Hey,
love the mod. Me and my friends just got started using it in our factory. We like the complexity and it makes it more enjoyable than the normal nuclear part of the game. However, we were a bit disappointed by the fact that the portable fission reactors just create an normal nuclear reactor with an output power of 750 kW. We were hoping that the more "costly" reactors would also offer more power (maybe around 1MW? So 2 would still create less power than 1 fusion reactor with 2,5MW. Would seem like a reasonable balance) or would take up less space in the grid. Unfortunately I cant really see any use in crafting these right now instead of just using 4 uranium fuel cells (which most likely everyone has plentiful at this stage of the game.)
I personally also feel like the plutonium bomb/artillery shell should be more powerful, but I guess just my taste for mass destruction. But maybe you would be into the idea of making some or all of these things a thing we could edit in the settings (other mods do this very well and I like the customizability)
But great work so far! Love the it!
