I haven't been playing Superhero-themed games for a long time, but something I've noticed as a recurring theme along the several I've dinked about on is that all of the major villains, or indeed anyone of any real import or leadership role, are all locked in a dust-gathering gun safe that only staff has the combination for. Some games won't allow you to play a villain at all, which seems to me like shooting yourself in the foot, especially if the game is in any way shape or form faction-based.
Does anyone know the reasoning behind this, or when this became popular? I'm assuming it's to prevent people from forming Mr. Sinister's Harem of Mutant Wives or General Zod's plot for the longest possible character squatting in internet history, but that's almost along the lines of "cutting off the hands of the musicians".
I've seen some games do this because they actively want to prevent PVP roleplay of any kind, but that's at the very extreme end, so I'm assuming that's the exception rather than the rule.
Eventually on these 'No Badguys Allowed' treehouses the game degenerates quickly into The Real Housewives Of Westchester County for lack of anything else to do: the street-level villains cluster together and the heroes cluster together and never the twain shall meet.
