Land treasure hunts and other random encounters (outside of ruins)

mind5torm_#7137

This poll indicates that a large majority of players would consider it an improvement if the game had random land treasure hunts (or other encounters) similar to the random sea treasure hunts like shipwrecks, mysterious islands, etc (e.g. "Mysterious Cave", "Ancient Ruins" etc)

This would add to the gameplay and immersion, improve consistency, and could also draw AI armies more away from settlements and generally increase the frequency of natural field battles (possibly as an at least partial alternative to mostly removing minor settlement battles).

This has also been proposed much earlier (for II): https://forums.totalwar.com/discussion/231080/the-game-could-use-land-treasure-hunts

I'd love more random events to spice the game up.
