My ideals:
1. The magic level isn't super-high. I'm willing to run Forgotten Realms if it's best for the other criteria, but I'd prefer something lower magic.
2. There are adventures available that readily fit the setting. I ran one Nyambe adventure one time, but the lack of sufficient supporting material made it impossible to turn it into a real campaign without a lot of work.
3. There is some kind of "home base" setting available, like a town or city the players spend their downtime and training time in.
4. It's D&D, 3.0 or 3.5. I know there are lots of other great games, but my players have Player's Handbooks and such, and want to play D&D.

Kingdoms of Kalamar all the way, IMO. Here's why:
1. KoK is a fairly low magic setting. There just aren't 20th wizards/sorcs hanging out in every city.
2. There are plenty of high quality adventures for KoK, many of them arced together to form mini-campaigns.
3. There are a couple of city supplements. Loona would make a good home base for PCs that need to lie low for awhile as the law is pretty loose in Loona. Geanavue, on the other hand, is a orderly city where the PCs could breath a little easier. There are plenty of adventures to be had there, but it's not the kind of place where assasinations take place on the streets in broad daylight. It's also a city of craftsmen, so it would be a good place for the PCs to go when they need to sell their swag.
4. It's not only D&D 3.0/3.5, it's OFFICIAL D&D. 'Nuff said!
