I recall that I played in an OGL game some years ago (still in the 3.5E era), but I don't remember its name. The premise was that each of us was a high level wizard (IIRC we started at level 20), but also ran a bunch of low level characters (1st level, I believe). The wizards sent the low level characters on adventures and plotted on the grand scale (though there was still a GM present), while most of the adventuring was done at low levels.
In any case, I am sure this would work in Pathfinder too. One wouldn't really need the game to run a campaign in that style, but still - Does anybody remember the name of that game?
