While taking a break from DSP, I went back into Factorio Space Age.
Just thinking about the trains for long distance large bulk transport. In Factorio it's definitely complicated: longer trains accelerate slower, accidentally mixing contents of wagons will screw you up, and throughput is limited to inserter speed and hand size. Plus trains cannot journey in the same place. One train must wait for the other to leave the tracks / station before another one can enter the same space. Oh, and burnable fuel is required.
Then in DSP, all 10 logistics vessels can immediately load and unload their max cap instantaneously, and while flying in and out of the ILS they can clipping stack on each other without touching. The only more troublesome limit is the energy recharge speed of the ILS.
Which sort of system do you like / feel is more fun for the game?
