Hi ;D
The main and propably best use is on aquilo.
In vanila factorio there are a lot of gas to be found on far ice platforms
You can't place foundation in amonia ocean and building bridges to far ice platforms is just tedious and boring
I Currently play in modpack and My primary use of Drones are in helping when expanding on Aquilo.
It works rly well when combined with
Aqulio trenches (https://mods.factorio.com/mod/AquiloTrenches) and Cargo ships (https://mods.factorio.com/mod/cargo-ships).
But the problem with drones is that they are too easy to obtain and build. Placing them in tech tree of some kind of planet is in my opinion good solution.
I was first thinking about gleba and placing drones behind carbon fiber, but drones fit's better in Moshine.
So that's why i am here
I agree with graphics, but i've seen much uglier mods. This one is at least kinda similar to factorio.
If time allow I will propably try to make mod that change tech requirements for Delivery Drones to gleba, to fix issue of "too easy to obtain"
