In 4e, it's part of being Epic (as [MENTION=22779]Hussar[/MENTION] posted).Where did this correlation between higher level and fame come from? A far as I know, nowhere at all is there any expectation that being any particular level has anything whatsoever to do with how well known you are, and it hasn't in decades.
But probably not in 4e. Epic Destinies are premised on the idea that the heroes are prominent figures.For every story (in fantasy or real-life) of a hero who basks in the rewards of fame, I think there's another story where the hero is unknown and unloved.
I don't agree with this at all. What does the d20 roll to jump represent? Stumbling on the edge of the chasm, a sudden gust of wind, etc etc (under ideal conditions no one's maximum jumping distance varies by the amount of a d20 roll in D&D).Your roll on Diplomacy does not dictate the internal consistency of the setting (in my game), it dictates how your character interacts with the internal consistency of the setting (in my game). So, rolling your Diplomacy successfully means you've convinced him, but it does not mean that he's heard of you. There's no "Fame" skill. Equating "Fame" with Diplomacy is houseruling
What is the equivalent of these random factors for talking to NPCs? Fame would be one of them. Visions of the impending arrival of demigods would be another (see below for more on this).
An Epic hermit PC may not be famous, but radiates holy power instead. Or whatever. As Hussar has said, different PCs and different skills can obtain their level bonuses in different ways. (Or do you mean not a hermit PC, but a hermit NPC who hasn't heard of the PC - maybe the successful Diplomacy reflects a vision the hermit had the night before presaging the arrival of this important stranger.)Hercules is epic, and most people know his name. What about the hermit that doesn't? If he still gets that +15 from fame alone, then it's not consistent. If it's from something else as well, then I don't think there's much of an objection.
But I don't think there's anything odd about fantasy heroes who have become demigods having the capacity, one way or another, to influence yokels without trouble.
