The play test went well. I managed to test all the things I wanted to test.
But what's the result? Well, the basic rules work nicely. Characters can interact with the world and with each other and an uncertainty is introduced. Some challenges weren't actually challenging, so I need to work the maths to make it harder. Some consequences weren't threatening (in fact, that was the word one of the players used… such good feedback).
I call that a successful play test. I went in with specific things to test and I came out with answers.
Now, back to the lab.
Also, I've almost settled on a name for the game. Won't take long to finalise that now.
