That's an easy point to make, and not an unfamiliar one. Mind you, it's usually being made by folks like BADD, with an anti-RPG agenda... ;PDeath is fast and easy. Tazers, force cages, sleep mist, sonic stun crowd control weapons - these are deployed much more rarely in rpgs compared to old knife in the gut, axe in the head, bullet in the brain or poison in the cup.
Seriously, though, the fact it takes even a teeny bit of extra thought to go non-lethal does help with drama, in that killing can be the expedient way of dealing with conflict, but not the best way. When killing is automatic, thoughtless, assumed - life is cheap - drama & suspense fall away, because there's nothing much left to care about.
