If at all possible please make it to where you could feasibly create your entire party from scratch and control all the characters dialogue in all moments of RP in single player. While many who played DivOS found it strange to RP two characters at once I for one rather enjoyed it and created several scenarios like a buddy cop duo, and a bickering married couple. Being able to create multiple characters led me to have a stronger attachment to them than I did to the companions. I'm certainly not against having companions, I mainly just want the option to make more than just one of the main characters so I can possibly make my duos (with two companions) again.
