and thought I'd leave a review.

I played only the "Coal and Steam" part of your mods, because I also felt like the burner stage was a bit too short in the vanilla game. This essentially delivers what I was hoping for: a meaningful pre-electricity phase.

Some balancing feedback (The mod developed rather quickly while I was playing so my findings might not be applicable in the current version.)
-Green science packs increase in complexity, but red ones do not, which makes for a weird moment where the 'lower'(brown) science packs are much more expensive than the 'higher' red ones. I guess you should also make red science a bit more involved to make the transition feel smoother.
-Steel and wood are a bitch. I was kinda surprised how much of my factory was dedicated to producing wood in the early game, and steel (including coal refining) in the late game. It feels like the productivity of these production chains is a bit too low, at least compared to other production chains.

Thanks for the feedback!

Yes the mod developed rather quickly (64 versions in 1 month :>), because I wanted to have all the things on my list included and with every new part in the mod an other part was landing on this list -(°v°)-, but this stage is now finished at least for Coal&Steam.

Can you tell me if you played the version with the "Wood 2" recipe or an earlier version? If wood is still an issuse I can look into it.

Yes, I agree that the transition from brown to red requires a bit more of something (tm). I already have some ideas, but they need more testing. I have yet to see how I can make this change compatible with bob / angel / sct / aai and space-exploration.

Okay, mhhh ... a bit more progress... I think I should make the recipe for tier 2 (processing with fluids) and 3 (processing with tools) a little more rewarding in the coal processing chain.

I had the wood2 recipe, and during play updated it to the version that required mud for fertilizer.

I will give you more feedback when I try a new game.

Thanks for the feedback!

Now there is nothing more important than the steam inserter. This is the first thing you have to think about, remembering this mod.
