This is the reason I don't mind the higher ones being quite a bit slower then the mark I turrets since that gives the I's a reason to always be useful as a stop gap measure.
The tech Is are still faster, the whole scale has just been slid downward by 30 seconds. So that should have the effect you want, I hope.
I think the main reason that I'm energy limited is that in an 8 player game, each player potentially has 1/8th of the number of planets, so 1/8th of the number of resources and energy. Resources however in single player games decrease by the number of them you have, so even in a single player game you're quickly getting to the point of maybe having half of the potential resources (due to lossage), but still 100% of the potential energy, wereas in multiplayer they'll have about 1/8th of the potential resources (because they'll be minimal to no loss), but a hard-ish cap on 1/8th of the potential energy. (If that makes sense?)
Well, each player in an 8-player game can build one reactor of each type on each of the 8 starting planets, so 24 reactors total per planet, whereas you just get the 3 at full efficiency per planet, so I see what you mean. Had not thought about that before. The resource lossage doesn't decrease at all anymore, actually, it's all based on the energy reactor costs now. So that's one thing that might potentially help, I don't know.
For example my forces were pretty much only Tech I's (in fact they were all I's except for the starships and whatever I'd parasited from the enemies, which wasn't all that much this time), and I was continually bouncing up against the energy limits even with 3x I/2x II/1x III per world.
The higher-tech ships don't cost more energy, actually, so that's another advantage you could use if need be.
I have the feeling there's something wrong in the balance here, I just can't put my finger on it.
Well, in many senses it is not supposed to be balanced, right? I mean, insofar as it is supposed to be distinct from the base experience, not just a multiplicative copy of it.
Interestingly enough, in this instance I actually didn't think of anything. Which is rather scary. O.o
It happens!
