I didn’t use half of the things i bought in the shop.
Train upgrades ? Not needed. You can just have 4 lines that go jump into the center.
Wires ? Not needed unless you make MAM.
Weird platforms shapes? Never. At no point was I limited by platform count.
Most of my play time was spent wiring up copy-pasted stuff in the zoomed out view, and the rest was setting up blueprints for each basic thing, and setting them up again but 3 times better, and again one last time.
Ideally the game should find some ways to make me want to use new things, even though I’m already going fast.
