Runequest Setting

[Utgardloki]

So I am thinking,

What makes a setting a Runequest setting? Compared to a D&D setting or a GURPS setting or D6 Fantasy?

I was thinking about a "Seven Worlds" concept in which each world would have a different game system. (I haven't figured out how to tie everything together. Maybe have some overarching plot that affects everything, even though different groups of characters have to complete quests.)

But how do I make the Runequest world a "runequest" world.?

Mostly you have to take some parts of the specific Runequest Rules into consideration into consideration: magic is very different from other systems for instance and also somewhat more accessible to all. On the other side, there is no such things as definitive classes like in D&D.
Above all, heroes are also less invincible, thus more humble.

For the rest it is very easy to create a setting just as it was made during the long existence of the BRPG: Cthulhu, Moorcok's multiverse, Glorantha, but also a lot of other setting which were developped here and there by non professionals (and sometimes available on Internet).
