@piratetrue enough, but while they're in a fantasy setting I believe they are also trying to keep things fairly grounded, and if you think of other natural resource generators, they actually suck in comparison to fuel based ones, and while sure, could do with a few extra geysers maybe, I think the balance is pretty good as is.
@bale, if its a pure oil node you only need 1 refinery per 5.6 generators and you can fuel 4 refineries from one pure node, which means one pure node will fully fuel 12 power plants. Cut those numbers in half for a normal one, ofc. And that's without over clocking. I can show you the math if you like.
But yes, in terms of raw efficiency, fuel based generators are better, especially with the lack of geysers in the map, but that's exactly the point, this is free power, it's not meant to be the main draw for your factory, it's only designed as a boost anyway. And sure some people will be too far from them for their main base to make any use of them, but in my opinion this game is designed for you to make multiple bases, (use beacons if you can't remember where you left them, that's what I did) outputting resources and then have them shipped back to the main hub, hence the train that's in its way soon. And through the course of making these extra bases at least one should be within range of some free power geysers.
