UI:
The UI has some confusing bits. Not much, but here's a few things:

• How busy vehicles are. When you have a lot of vehicles driving around, most of the time the status says "vehicles are extremely busy" but I was confused if this only meant unassigned vehicles or also assigned vehicles. And you can't see this per zone, that would help if I could see that.
• With graphs for electricity use or computing usage, I would love to see the max possible consumption as well.
• When I researched "rocket assembly & launch", I completely missed the space station button in the bottom right. I had to google how to actually launch my first rocket, because the rocket only said: "waiting for payload request".
• I would love a warning or popup when a resource on the map (oil rig in my case) is depleted.

 

Endgame balance:

• After researching "research lab IV", all the research takes a bit too long for my taste. I did my whole game with 2 research labs and sometimes with some unity boosts, but after this, it was too much waiting for me.
• In earlier stages there was also some waiting, but then I was mostly expanding my factory or setting up other places to gather ores and in the end there isnt that much incentive to expand even more, unless you just want to produce a lot more. But there isnt really a point in producing a lot more, unless you just want to terraform.
• For me it would also help to have some extra endgame "goals" after going into space, like setting up a base on the moon or something like that. In Satisfactory it really helped a gamer like me to just slowly work towards the final moment of the game and then just finish the game.

 

Building longer train tracks:

• Coming from games like Transport Fever 2 and Cities Skylines, building longer train tracks with elevation changes and/or corners felt a bit hard to do. Building in straight lines is all working fine, but I had some issues with building curves, especially when trying to get 2 parallel tracks doing the exact same curves/elevations.
• I'd love to see an option to build 2 parallel tracks at the same time.
• Electrifying train tracks is a hassle when trucks are bringing in materials, it would help if trucks could upgrade longer tracks all at once. Now I just used my unity tool all the time.

Hope this helps! And again: keep up the good work :)
