Hex Stocking Density
For interest sake I pulled out one of my copies of Isle of Dread. For most, it is the benchmark for hex-crawling modules. I wanted to approximate the ratio of hexes-to-encounters. Using the methodology mentioned in my last post there is a 1-in-3 chance of a hex having a monster for a hexes-to-encounter ratio of 3:1 which gives me approximately 133 monster encounters in my 400 hexes.
Just eyeballing the number of hexes on the island, I would guesstimate that there are approximately 400 hexes (has anyone actually counted them? I am far too lazy). Using the numbered island map from the module which as 24 encounters and adding 5 for the number of locations on Taboo Island, there are a total of 29 encounters on the island. Let's round up to 30. I am assuming that all numbered encounters on the map are with monsters which may not be correct. I took a quick look and didn't see any exceptions but I could be wrong. This gives a ratio of 13 hexes to 1 encounter.
My hexes are far more densely populated with monsters than those on the iconic island. I'm okay with this. One reason I am okay with a higher number of encounters on my map is that it is for an open, exploration focused game in the West Marches style. I want the PCs to go out into the wilderness and find stuff. Also, the there is an explicit social contract that characters will try to return to town at the end of a gaming session so the quicker implied consumption of resources that will result from more encounter will not be an issue.
