Continental/planetary hex crawl? (Starfinder 2E)
I'm planning to run a Starfinder 2E campaign in the near-ish future with a lot of wilderness exploration that I'd like to run as a hex crawl, but I'd like some advice on prep/scope.
The players are going to be departing from a central hub city and searching a planet's continents for dungeons (basically). They'll have a rough idea of where each dungeon might be located, but they'll need to travel through wilderness to reach each estimated location and then find the dungeon itself. I'd like to run this as a player-visible hex crawl as neither I nor my players have yet been satisfied with more freeform exploration/travel systems and I've always wanted to take a crack at one.
However, I'm struggling to figure out how to plan/prep a continent-sized hex crawl. They'll have relatively speedy travel options so I'm estimating ~50-60 miles a day, which I'll be using an excuse for bigger hexes to reduce the overall count (planning for 1 hex = roughly 1/2 day of travel). Currently I'm considering having explicitly location-dependent things keyed to individual hexes and all other "regular" hexes tied to random tables with different tables for each biome/etc. I'm fine with having a rare empty hex here and there.
Is this a reasonable approach? If not, what better options/approaches are there for running this? Thanks!
