What if assemblers only assembled? This is an overhaul mod that introduces interesting production chains and design choices. New ores, new concepts, new assemblers, new intermediates -- and new challenges to overcome.
Maybe add a 1x1 or 2x2 assembler, which can only craft basic items (eg, transport belts, chests, repair packs and especially Red science). The early game is kind of a slog, because to progress you need red science, but you can only craft it in an assembler, which needs galvanised steel. adding a minissembler would make the early game easier and better(?) because you can automate red science
Wait, sorry. You can craft load bearing items from the start, but they don't show up in the crafting menu so it was confusing. Maybe show them in a seperate tab or something
