Because all the races available to a given career are displayed on the card how will FF go about adding more player races.
My guess is by a quick description e.g. Bretonnians can choose any career available to Reiklanders except career that are ONLY for Reiklanders.
Also Bretonnians would have some special careers such as squire (a starting career) or knight (an advanced career)
Other races might be more restrictive such as:
Lizardmen cannot choose any careers except there own (mage-priest, champion etc.) and a few exceptions (scout, soldier)
Any ideas?
