I’m currently writing a ChoiceScript game for entry into IFComp (https://ifcomp.org/), and it’s at the point where it’s done enough to have beta readers. Now, the thing about IFComp is that judges are supposed to only rate the games on the first two hours of play, which is a problem, since I’ve had at least one beta tester estimate their play time at about 2.5 hours, while I played through it on my test run in about 1 3/4 hours. Clearly, I can’t appropriately yardstick my own game length.
My first thought was to just go look up “average reading speed” and then try to figure out the average playthrough length, but I also don’t have a good idea of how to estimate the minimum, maximum, and average word counts of a playthrough. So I’m unsure how to best handle this.
So, are there any best practices around estimating the average playtime?
