This issue mainly dominates the Resources tab:
I’ve seen a lot of people have issues with the crafting and gathering in relation to the starting inventory size. Though you can technically upgrade your inventory right as you hit Sacrament, from a player’s perspective, it feels quite terrible to spend your first upgrade on just your inventory.
I believe this will lead a lot of players to struggle with inventory management for the first 5-10 hours of the game, with the only indication of storage being upgrading using precious blood vials or using the community chest.
If citizenship (or even just storage chests themselves) in Sacrament was hinted at earlier, perhaps through a side quest when you first arrive, this could better set player’s expectations for what is to come, potentially reducing player frustration with inventory management or the blood upgrades system and drive them to push a couple quests further in the story.
