Yeah, I'm with Strolen. Sure, it's a stereotype - and how many stereotypes do we routinely employ, anyway? - but this EXPLAINS the stereotype. Too many people are far too ready to turn their noses up at subs that don't hit minimum (but undefined) levels of Quirky!, Flashy! or Unique!
Beyond which, c'mon, folks ... what's the psychology behind an adventurer, anyway? Who goes off from living nice, safe, quiet lives to run off and deal with horrors on a regular basis, sleep on the ground in haunted ruins and pretty much be assured of an early, violent death unless you have at least a little crazy in you?
