Hexcrawling Alone in the Wilderness is a hack of Takuma Okada's Alone Among the Stars.
This is a journaling game requiring one player, a pack of 52 standard playing cards and a six-sided die (1d6) or another suitable randomizer.
You are an explorer, randomly travelling through the wilderness regions at the borders of civilisation. You travel to new hexes, making a note of what you find in each place, both terrain features and encounters. You find many things in your travels, and experience dangers as well. Some places you venture to have features worthy of further, more detailed exploration. Whether or not you choose to explore these features is up to you.
