Well, there’s no reason why the DM couldn’t hold the character sheets and you only perceive that your character is good at certain things from your choices and their outcome in the scenario (but you could be wildly wrong). In real life you don’t know exactly how many charisma points you have.
Reviews of some indie games were bought, it was asserted, because the games involved just wandering round a location investigating things (i.e. the diary notes in Resident Evil and System Shock) and didn’t even let you collect experience points like a proper masculine game.
I don’t see how stating the blindingly obvious makes him “epic”.
