Could i propose a middle ground? No real system but still character skills and rolls. Everybody picks 5 specialities in which he's good at. When there's a conflict involved, we simply roll a dice to check if it's a succes or not. The GM decides what's the % chance of succes is.
In combat, rolling a succes two times in a row means defeating your enemy.
If someone wants to, he can take a speciality two times to represent he's really good at something. No numbers, accept for the GM to roll.
