Progression beyond unlocking new ways to play the game (such as in FTL) almost immediately kills any interest I have in a roguelike/roguelite. Or really most genres that it's infested.

What happened in the last 10 years that every game now needs to drip feed constant rewards rather than just being fun enough that you come back to play it?

IMO the beauty of a roguelike is its impermanence. You pick it up, play for awhile, and if you lose the slate is wiped clean for next time.
