Just a few minor details that I found odd while trying to immerse myself into the game world (which I love so far.) Some of these may be impractical to fix for PoE at this point, but maybe you can take them into consideration for your next game
Names Prescience
Hovering the mouse over NPCs shows their name before our character even knows who they are. Maybe Expert Mode can include an option to disable that and show names as "???" until the character has introduced themselves? Not all conversations begin with an introduction though, so this may require changing some of the dialogue to include them. Right now I'm working around it by assuming it's because of our special powers
Permanently Unsheathed Weapons
Does anybody else feel awkward walking* around in public places with your flaming swords and shotguns out at all times? An option to sheathe them would be easy to implement and make us feel more civil.
Always running everywhere
Speaking of walking, how come we can't ever take it slow and just stroll at a leisurely pace? A middle ground between the constant running and sneaky scouting. While we're at it can we get an option to disable pausing when we open the journal? It'd be nice to read stuff while the party continues to its destination.
Stronghold
Right now the whole stronghold mechanic feels kinda tacked on, especially the very first construction that gets completed in an instant. Maybe have a narrative vignette introduce the event as a part of the story, instead of having it just happen like that through the UI? And where are the people that carry out the constructions, our "patrols" and stuff?
