7. Going with party mechanics again, in Knights of the Old Republic some NPCs had unique abilities, which made playing without them impossible, thus forcing players to have them in the party (only T3-M4 can open the Sith base, only Mission can open that force field, etc.) At the same time, the nature of those abilities was hardly unique: all characters had access to Security or Computer Use skills, yet your skills, no matter how high, would be useless in the above mentioned circumstances. Do you feel it was the best way to make NPCs more important?
