Just some notes:
- It seems to be very poluted. But it was a lot worse. The only things that run on full speed modules is the oil area in the south-west and the coal production in the north to make the not neaded coal much faster desapear for the last pieces of my "formed" solar farm in the north. Coal and iron in the middle are running without effency modules what is the main reason for the pollution in the north.
- The main area has changed a lot over the play of the map. There where times the dark red area of pollution went a lot over the lake in the south-east. But now nearly everything in the main area is pushed down to -70% with a small and a middle effency module. The pollution decreased a lot. But I never had issues with the biters.
- The name sign has a width of 33 "pixels" and each pixel has a width of 2 solar panels and a gap. 34x7 = 238 tiles wide. Even with construction bots it took a while to construct the right way. You may notice the first try in the east I didn't finish yet. It has only a pixelsize of 6 and half of the pixels. Only the J is outlined with belts.
- My main issue with the map is the rare iron. At the moment I can fill two slow belts coming into my iron smelting area, but it will not stay long. Every orefield is so small... By gaining iron I also get a lot of copperfields and there are a lot small and bigger ons still inside the walls. Coal I don't use for anything else than plastic, therefore the fields are a waste (why is there no receipt to turn coal with water and a bit of magic into oil? )
- For expansion I might gain the rest of the area to the east up to the lake in the north-east (because of iron and oil), but then I will discover the south-west. I might expand the wall to the lake in the south-west, but then it might be that I build my first train. The main incoming station will be south of the copper-smelting. Hopefully somewhere in the south-west are some bigger ironfiels.
