Mutant: year Zero (another Free League game) also has a cool home base mechanic deeply incorporated into play.Has anyone played Forbidden Lands? From my understanding the game is built around characters having a stronghold from level 1. Vaesen, another free league game, works this way too. What's appealing is that the home base can be upgraded and provides certain mechanical bonuses (BitD works this way too).
That said, I think there is a certain fantasy around being able to just carry everything you need in your backpack, traveling the world with your friends. A stronghold game that is merely home design invoices and taxes will not be that appealing by contrast.
But, we are talking about D&D, and specifically how D&D had an in-built change of playstyle over the course of the campaign.
