This is going to be one of the topics for tomorrow night's recording of the Brainstorm Podcast - creating sub races for pre-existing fantasy races.
Do you use sub races (grey / high / wood elves and the like) and if you do, do you create your own?
Do you prefer to stick to just the default version of the race? Why or why not?
Are sub races purely flavor, or should they have a game effect?
Let me know your thoughts - and you can hear mine on the podcast ;)
