Instinctively I prefer game systems that are based on rolling high. Just how I'm wired I guess.
The thing is, even the system I cut my teeth on wasn't all "Roll High". AD&D is roll high for attacks, saving throws and damage, but it's low roll for thief skills, general hear noise skill and opening doors.
Of the percentile based systems, Runequest is pretty much roll low, WFRP is roll low if I recall correctly but RoleMaster is roll high. Actually, I think RM is more of a "Roll High" system than AD&D is. I should like it more than I do, but that might be tempered by the the shitload of charts in RM.
I'm wondering why I personally have an issue with "Roll Low" systems and subsystems when I've been using them for the last 30+ years.
