The Swedish RPG "Drakar & Demoner", which was based on Magic World, but later developed along its own lines (but still always has been clearly a BRP-engine game) used a different table in its 3:rd ed. (from 1987).
Code:
01-16 No extra damage
17-20 +1d4
21-25 +1d6
26-30 +1d10
31-40 +2d6
51-60 +3d6
61-70 +4d6
71-90 +5d6
each additional
+ 20 +1d6
Then in the 4:ed (from 1991) the game designers changed the rules again:
Code:
01-26 No extra damage
27-29 +1
30-32 +1d2
33-40 +1d4
41-50 +1d6
51-60 +1d10
61-80 +2d6
81-100 +3d6
101-140 +4d6
141-180 +5d6
They also upgraded the damage two-handed weapons did. A standard human wielding a Greataxe normally did 2d6+2+1d4 points of damage in RQ III (with an average of 11), in D&D 4 (as its known in Sweden) the same human would do 2d10+1 (for an average of 11). Creatures that where strong (such as dwarves) benefited from the new system since it only cared about whether or not you could handle the heavy weapon (i.e. the STR value).
