You hate it Ash? It's in twelve games in my dataset, but the most recent of them is a parody of older games and calls it "Dumb Luck," and before that the most recent is from 1998. I think RPGs have mostly moved beyond the idea that Luck is a fundamental human engagement with the world.
@paulczege I always good annoyed by the idea of luck mechanics because I felt like it confused the line between the artefacts of play such as dice and the fiction being negotiated. These days though I mostly find it boring. Complete Scoundrel was my least favourite 3.5 book cause it felt like scoundrels weren't clever or far skilled but rather just "lucky"
My problem with Luck as a stat was that it was either too borad or too narrow, but never just right. Luck could apply to any and all uncertain situation, in which case it was clearly better than all other stats. Or a GM might only let you roll Luck when no other stat applied, in which case it was clearly worse than all other stats.
(A few games got around this using different mechanics for Luck. Feng Shui's Fortune stat was bonus dice to add onto another attribute.)
