There will be companions. I hope better than the FO3 companions.
Personally, I enjoyed the level of depth of character of the DA:O companions. I saw ;the development of those characters as a step in the right direction for player character companions.
Take them, or leave them, players choice. Companions should not be forced onto the player, unless somehow they are part of the plot/story.
In Todd Howard's reply to a question http://theelderscrollsskyrim.com/bethesdas-todd-howard-podcast-interview/ (at 25:10), there is the oddly placed, perhaps, off-the-cuff comment that states:
...And there still will be some like that..."
I believe that strangely placed phrase means there will be some characters with "...deep personalities and uniqueness..."
I would like to know more...
Nice find on that podcast quote!
I use companions every once in a while, but would prefer deeper and fewer companions than plenty of lackeys with no personalities. If I wanted that type of companion, I would just make my own in the CK so I could make them how I want and come up with a backstory on my own.
I liked Mass Effect and DAs companions for that type of game, but the system of raising approval and such is pretty easy, it should be hidden from the player's view and only visible in comments, not an obvious bar.
Hopefully, if they do go for a few deeper, storied companions they will comment or interject in conversations and decisions to remind us that they're around. Smarter AI as well, they can be dumb as a pile of bricks sometimes, at least give us some interface to issue orders to them like pick lock, sneak attack target, heal, etc. They need to be
kept optional as well, some players won't want them and stealthier playstyles don't work well with them unless the AI is revamped quite a bit.
