I wanted to leverage the permadeath aspect of the game into something that would support much longer-term play. The heart of this was turning the vault into an expandable house. You would be able to retire your characters for a bonus (rather than having them die), and live in the house – with the number who live there based on what you’d paid to expand the house, of course. There was to be a cemetery where you could see your old, dead characters, an expanded pet yard, and a trophy case (itself a call-out to the very first text dungeon adventure, Colossal Cave) where you could keep heirloom and other items.
The heirloom items were ones that you could keep across characters. They would last for a limited number of lives (that you could buff, naturally, to get them to last longer) and that helped each class in different ways. The more parts of a set you collected, the more powerful they all were.
This plus additional lands, the ability for players to create their own dungeons (and earn in-game cash by selling keys)… lots of things.
I should say too that this is how it is with almost any game: the designers inevitably have a huge backlog of things they want to do but never get the chance. So it goes.
