Would you care to satisfy my curiosity and provide an opinion?
People use the terms high- and low- but they don't always seem to be talking about the same thing. What do you consider a low magic setting and what is a high magic setting? Why does the difference matter to you?
It's really just personal opinion, I've always found overabundance of magical items, spells, or locations unsatisfying. Something about "Oh, there's another Wizard." or "So we travel to the flying fortress with our rings of Levitation..." that bothers me.
My absolute favorite setting is the Warhammer world, which isn't really -low- magic, just extremely dangerous and twisted magic.
As far as what I define each as, high magic is something like the Dungeons and Dragons Forgotten Realms or The Elder Scrolls settings, while low magic would be the Song of Ice and Fire setting or Middle-Earth. The actual separation between the two doesn't mean I'll automatically like or dislike the setting (Not a big Middle-Earth fan, but I like TES).
As for the responses, I appreciate the clarification. One thing I like about this is that it makes sense in the cosmology, rather than just "being there".
