In the Kickstarter stretch goals, a player house is mentioned:
However, no mention of whether it's just 'a house', a hideout, a base... whether or not it can be upgraded or not. I mean, it seems like you can adjust the furniture and so on -- but perhaps it could be upgraded in other ways too -- both functional and aesthetic?
For example:
Going from a shack to a city mansion would not only lend you extra storage space, but perhaps have companion-benefits as well. And I wasn't thinking specifically of 'romance', but your companions might be in a better mood if they were sleeping on real beds rather than on the grass. Perhaps paid companions would be much cheaper if they had a place to stay for free as well?
Depending on how notorious or infamous or wanted you are, picking a place that is well hidden might lend you additional bonuses as well. Perhaps buy you some time to avoid bounty hunters, or even to protect your stash(es?) from thieves.
With a full estate or some 'training grounds', perhaps there could be benefits to skill gain or for one companion to teach another companion some skills?
Perhaps your hideout, base, or estate could be upgraded defensively, so that if you were attacked by either would-be mauraders or a small pursuing army, you would be able to fend them off or defeat them?
If multiple locations are possible for these things, perhaps in your 'home city' you could own an estate, but in more dangerous territories, have a cave hideout? Maybe your archmage companion, once you've gained his trust and pursuaded him -- could seal it with a stone, for example.
