I'm trying to create a battlemap that I can change on the fly based on players' decisions.
Firstly, I know this sub is mostly for in-person, physical objects. I play online over Roll20. But I need the kind of creative solutions that DIY-ers like yourselves are good at, so I hope this post isn't too out of place.
I have an ambitious idea for a one-shot that involves my players creating a world as they travel through it. At certain points, they will be asked questions that shape the new world being born. "You see a terrifying creature, what does it look like?" "You find the perfect place to rest, describe it to me." Now I'm wondering how to handle the battlemap.
Of course, the easiest way would just be to rely on theater of the mind. But I enjoy making detailed maps. My other thought is to try and make as many "themes" ahead of time as I can think of and just pull out whatever is closest in the moment--a desert map, a swamp map, a city map, etc. Does anyone have any other ideas?
