Yeah, I am thinking back to those early games which were far more survive it if you can. Later, it has become more kick it's ass because you are powerful. The GM's NPCs have to try and survive the PCs! A complete turn around.
Given the overwhelming presence of superheroes for the past decade (or two decades), I find claims that the continued success of fantasy RPGs to be solely due to power-tripping to be somewhat suspect, at best. Or, at a minimum, lacking in foundation.
But that's just my opinion!
