I really, really wanted a non-violent mode in Far Cry 5 for my son. If a mode that removed the hostiles and weapons had existed I can guarantee that would have been my son’s (he was probably about 6 at the time?) favorite game for a couple years straight. Flying and driving around rural Montana landscapes, fishing, watching wildlife? He’d have spent 20x more time in that mode than I did beating the game ordinarily. Super bonus points for two-player local multiplayer so we could play together.

(It came frustratingly close to this if you kept playing after beating the game, but there were still guns and still some hostiles wandering around, IIRC)
