Another question would love if a DEV would give some clue.
In Baldurs Gate (and later in NWN2 and other similar games) it became popular to allow characters to rise in power and eventually earn, buy, build or take over a stronghold. This could be in the form of a wizard tower, a thieves guild, an old castle, etc.
Other than the player camp which will expand as the party grows, will there be any such achievement and home base in BG3?
