Problem is it's so early in development and we all have our own visions for the game I suppose. For me, programming competent companion AI, especially in an open world environment is not only very hard to do, but it's not really worth the effort in this case. The focus should be on us, the loner, with tenuous alliances maybe, but nothing so permanent as a gang of friends tagging along to help us. If I want to play a true party-based game I go find an old school infinity engine title or something by Bioware.
