Hello,
I have not played Moonshine yet, and i was thinking, if moshine adds a science, you could lock it behind aquilo and moshine science.
You have surly thought of this.
i can't think of anything more right now.
Thanks for the mod

Hey. The problem with that is: If you have been on Moshine already (it is unlocked before Aquilo), you unlock 2 tiers basically at the same time, skipping one. That should not be the indented way. It could be locked behind promethium though.

mmh i see, could the black trains (T3) be unlocable with volcanus (or multiple inner planets) and maglev on aquilo + moshine?

I see a problem with multiple tiers between Nauvis and Aquilo: The planets have no natural order. If you visit the planets in a certain order, you'll skip a tier. I don't think that's a good mechanic.

i guess it is for people that do not wanna play with moon moshine.
Maybe if you patch the maglev to promethium science yeah :D

I think I'll add an optional 4th tier being able to use both Maglev Trains (https://mods.factorio.com/mod/se-space-trains) and Electronic locomotives (https://mods.factorio.com/mod/Electronic_Locomotives) depending on which is installed.

Good, sounds like the only way.

another option might be having electric/battery powered versions for each tier, as sidegrades. perhaps having the batteries have lower acceleration to make up for the ease of fuel.

then you could make black trains and maglevs both get unlocked on aquilo, as side grades to eachother, while basic electric trains get unlocked on fulgura and the steam trains get unlocked on vulcanis

no idea how difficult any of that might be to implement though
