Typically, RPG party members serve a purely tactical role, giving your more bodies to control in combat and access to different combat abilities. In a sense, you’re role-playing an entire squad as outside of combat there is very little (if any) difference between the character you created and the characters you’ve recruited or created next.
It works great in RPGs that are mostly about combat, but calls for a different approach when it comes to non-combat gameplay. The main problem is that party members offer nothing but combat benefits (occasionally, freaky sex to relieve combat stress and party banter), giving you very few reasons to treat party members any differently than the main character.
In short, the problem is that in most RPGs party members are mindless zombies lacking any free will, agenda, goals, etc – the very qualities that separate an actual “character” from a zombie. Thus, our main design goal is to create proper characters that have a will of their own, as well as agendas, beliefs, goals, and other infuriating qualities.
