I've resisted adding new larger containers for a while because there are some standalone mods that already provide these tools to you. The problem is that I find they don't match the style of the rest of the game.
I'm not really sure why, but a little while ago I just felt inspired to make a set of larger containers that are based directly on the game's own containers and other assets.
The examples here are the logistic storage set:
Storage Chest (1x1)
Storage Strongbox (2x2)
Storage Storehouse (4x4)
Storage Warehouse (6x6)
I still need to work on things like destroyed version graphics, recipes, etc.
I'm unsure if these will be part of AAI Industry or a standalone mod. Currently I'm leaning towards them being part of AAI Industry at first, then also released as a standalone mod but without being removed from AAI Industry.
Update:
I released it standalone at first.
Would anyone be interested in a 8x8 version with 800 slots?
Also as the mod has been released I'm making this post public.
