Thanks for the idea yeah that would work. But making stories is not my strong suit so I would prolly need to ask for someone's help XD
you have set everything up with people on horse and evil barabrians. I know barely anything about rpg maker but you could make a very cool game where you move the 3 people on horses with WASD UHJK en the ARROW KEYS. and then you make some kind of fast horror game where the barbarians are trying to eat you. it would be chaotic fun if you do it wel. just an idea for inspiration, do whatever you like as long as its fun.
