I'm not sure if this belongs in rules or general, but one thing I really like about MYZ was that each skill had a success and a failure blurb. For example
FORCE:
When wreckage or debris block your way and you need to push or lift something heavy, roll for Force. Use this skill for any feat of strength.
Failure: It’s just too heavy. You need tofind another way. And what if the noise youmade attracted unwanted company?
Success: With a groan, you push through and get whatever it was out of your way.
Stunts: If you roll extra/beyond the first,choose one of these stunts:
KYou push or throw the object with great force. One target of your choice within Arm’s Length su ers damage equal to the number of extra/.
KIf applicable in the situation, you find or reveal a hidden passage or object. The GM decides what it is.
p.s. Will FB have stunts?
