My first reaction to the races in Radiance is "No way am I allowing all of those races." Now I realise that it is great that these options are in the free core book. (I hope WotC is reading this.)
I'm writing notes for my Radiance campaign, and the new Radiance Masters Guide makes that easy. This is not a simple rehash of the many GMGs of the past; it is a great guide to making the creation of adventures so much easier.
Yeah, the idea is that even for a cosmopolitan setting, the GM will strongly encourage particular races, say, a half-dozen to really help set the flavor of a particular campaign. They're just options.

As a GM, these days, I have so little time in my life to put together adventures. So why not give folks as many modular pieces as possible: stories, creatures, maps, townies, etc. To be honest, for most games now, I just select and print various materials that I think will fit the adventure I have in mind for that game day, and just throw in what I need as we go to meet the needs of the story experience.
