Aside: The Maths of Fighting Fantasy

This blog, at least in name, talks about the maths of RPGs. Most of the time I actually just want to talk about RPGs, ideas and what happened the other night at the table, but I thought the following video was worth sharing, as it follows on a little from my post about Murderous Ghosts from last week, and also from the post that noisms made about us playing it at the weekend.

I'd recently been thinking about doing something similar to what this video does with Island of the Lizard King, which I found in a charity shop, but there is no way I could do it as much justice as this video does.

One follow-up question does occur: I wonder how much difference there is in the graph structure of the various Fighting Fantasy books?

And another interesting problem that might be do-able: what is the probability that a person actually makes it to section 400, given the skill/stamina that they start with?

There's some work in figuring that out, but it's essentially coming up with a general formula for calculating the odds of surviving an encounter, and figuring out the various general paths through the book (taking into account when you come across things like traps that you have to roll under skill or suffer penalties). To solve it you would build up a couple of general results, then plug in numbers. Not simple per se, but not hard... The actuarial tables of the Island of the Lizard King...
