imo the great thing of MP is that the ingame AI would not be something for the user and devs to need to worry so much as any current npc in single player could be a potential real player, any Trauma Team character, NC Police officer, food stall seller, club bouncer, any Valentino, Tyger, anyone could be anything... the gamer could be playing a "single player" game in a multiplayer mode. Organized factions created by real players, real fixers... I think there's a lot of potential here to be honest, the key here would may be perfecting skills in Single player before diving into MP as a Merc in example, or you could start playing in MP right from the bat as a homeless and try to raise your stats, but that would turn out a lot more difficult since you`d be playing against legendary NC mercs from the beginning.. food for thought?
