I’m a bit confused about why this system claims to be based on the classic x-in-6 mechanic.
It’s stated in the blurb, and again in the text. Then the text describes a roll-over mechanic, which x-in-6 is not (it’s roll-under, that’s why it’s called “x-in-6”). Then when it finally describes the actual DAD6 mechanic, it’s a dice pool. Completely different.
