Excuse me, but I'd say you persistently mix up two different things.bobucles wrote: ↑Sun Jan 06, 2019 2:55 pmAdvanced oil is going to get rushed. The current tech tree demands more petrol than basic oil can ever provide. <...>
There are only two in game tech solutions for this. One breaks down the petrol barrier all together and gives an unlimited supply of petrol so the player never has petrol problems ever again. The other gives a tiny boost of petrol, but it kicks the player in the nuts for daring to build a factory. [The second] choice isn't good enough to justify using, and that's just bad.
If you are setting up coal liquefaction to get more gas, then it shouldn't bother you that you lose in terms of energy. That's not "kicking in the nuts", that's a reasonable decision that a player can make depending on what he currently needs more: energy or gas.
If anything, it seems to me a better game design decision, as it doesn't compulse players to switch all boiler-destined coal into liquefaction every time in every situation, but gives an option that depends on the needs.
I agree that it's an interesting idea to move coal liquefaction much earlier in the tree, and also, as someone suggested somewhere on the forum, move AOP later in the tree, and also make it a bit less net oil output (but more total gas after cracking).
But I see no substantial reason to make coal liquefaction energy-positive.
