I've been playing the new version and I like the changes, especially the secret actions. It adds a level of exploration to the game that it lacked before. Perhaps in the future that same mechanic could be used to improve and deepen other Renascents? So you'd basically receive a quest from a fellow Renascent (the artist dude wants exotic painting materials from beyond reality or something) and then the secret/rumor mechanic would be used to find them. Doing that quest succesfully would give the ally Renascent a permanent boost.
Sometimes the game starts with the society already collapsed. Is this happening on purpose or is it a bug? I always start as an outcast and getting 100 arkhe together with a collapsed society is almost impossible.
I think there are still sort of...negative feedback loops in the game that are hard to break out of. They can be frustrating. Basically, I mean things like weariness increasing so high you can't do naught but combat it, especially once you start getting bad qualities. Same thing applies to high tension or running out of merits. I understand that the nobles offering "help" are a partial solution to this, but maybe they should trigger more actively when you are trouble. Plus making fey creatures could offer to make really bad deals too? Maybe dying and being reborn could reduce the tenson level a little? Maybe you could spend a lot of one resource to solve the problem with another, like spending a lot of Arkhe to lower tension?
Regarding playing on after winning one instance, maybe more could be carried on? If not resources or abilities, maybe knowledge about fey and secrets? Perhaps make it so some enemy renascents could carry something on as well, dynamically creating nemesis for you?
