Some of my players are still on the new side, so a lot of times if I’m going to force them to spend checks to complete the mission, I’ll give them an up-front warning. Nothing major, but just something like, “just so you know, dudes, you’re going to want to earn some checks for the PT.” I’ve actually found that it also helps players to understand and internalize how to earn checks if they know that they’ll be used. Otherwise they end up with their free check, blow it on something stupid, and we’re back to the GM turn and they’ve learned nothing.
