Hi,
Nice to see this! To bring this further perhaps we can also encourage the use of supply trains. Consider this nice read: https://www.reddit.com/r/factorio/comments/17gxkae/huge_player_inventory/
I think either reduce player inventory or reduce stack sizes of certain items will be helpful to get more immersion. Imagine if the assembler stack size would be 5 for example and the Nuclear reactor would be 1.
