I taken the main bus design and compacted it a bit. Some people also modularize their production and use trains to cart it around. Man Bus designs tend to be more forgiving and allow overflow from lanes, etc. The upsides of spaghetti factories are that they look really cool! Also, the speedrunners use them since they can conserve resources by making exact ratios for things they are producing. Newer players tend to play in a spaghetti-like fashion. Originally posted by Sane:If most use a main bus, what does the other players use? What other alternative do we have? I've always wondered, since I've only used a main bus design.
