I'm about a dozen hours in, early game, and the third data card is ticking over nicely. I can't remember any mod that's grabbed me like this one - it's magnificent! My only problem (okay, 'latest' problem) is that the cube spends (seemingly?) most of its time in the boiler. A 'green' tech that buffs the boiler would be very useful. Maybe it could require some chemistry for the boost? Anyway, it's looking like a long slog as I limp to nuclear power with the factory starved for materials about half the time, and not much I can do about it(?). I suppose I'll be off clearing cliffs, filling lakes and setting up core mining and rail blocks. Maybe the interlude is fine.
