I love this, it is going to help me flesh out the idea brewing in my head. It is so simple it is pure genius

I really enjoy the three Approaches! My love of alliteration leads me to suggest as alternative terms - Direct, Discrete, Device.

you know what! this is fantastic and I would like to update to these terms! that ok by you?

Yep, go ahead and use them! This will be my small contribution to a cool ruleset :)

Thank you! It is done and I though I had replied to you about it before :)

clarification on the phrasing used to explain directly opposed tasks:
do u mean that players/characters must roll under their stat and higher than the oppositions roll?

quite the contrary:

when you make opposite rolls, the higher roll wins

if either side rolls below their own approach score, they use their approach score instead of the dice result.

so in an opposed roll, if my approach score is 10 and I roll a 7, I'll use 10 instead

"Each player ignores a result below their own score and uses that score number instead."

With your explanation in-hand, this line in the rules now makes more sense, but on first read it wasn't clear to me. It might be helpful to use language closer to what you wrote in the comment above.

This is a subtly brilliant mechanic by setting a floor for the character based on their natural ability in that approach, but still allowing the opponent to get lucky and roll higher.

thank you! I will try to clarify the text there!
