I’m thinking all the other civs are demons. The trick is the player/slayer can only destroy thier cities, not capture them. So the only cities you can actually have are player made. The rest you rip and tear through.
Chrono Trigger is definitely longer than Mario RPG and twice that because of all the multiple endings.
Harvest Moon is 25 hours.
Earthbound is 30-35.
Dragon Quest 5 is 30 hours.
Final Fantasy 5 is 30+.
The list goes on.
The reviews for this game are saying it’s 10 hours.
