I'm #writing a #ttrpg adventure for my son revolves around space exploration (with combat, of course :) ).

We tried #traveller and #gurps before settling on #starfinder - he's familiar with #dnd5e so we kept along that theme. It's an origin story of sorts as it's not set in any pre-existing campaign world. Here's a portion of a #battlemap I've made for it in #gimp and #campaigncartographer:
@Thelgor Have you tried Dungeondraft at all? That’s what I use for map building. Costs a little bit but resources and tutorials are available.
