dtgreene: I am curious what games are out there that take place in common magic settings.

A common magic setting is one where nearly everyone can use magic (or something like magic), and the inability to use magic. if present in the setting, is rare enough to be notable. In particular, if a character is unable to use magic, it should be an important part of the plot.

Here are a few games I know about that are like that:
Saga Frontier 2 (Gustave's inability to use magic is an important plot point, and everyone else can use magic)
Dark Sun games (if you count psionics as magic)

Any others?
