I can understand the pain with Voice thing, and for me, I actually understand why it's not there. They are not a triple A studio, so they can't devote resources to that, not atm. Not with how much dialogue this game has.
Hopefully on release there will be more character customization options available.
As for other NPC's being involved, idk how they can add a safeguard, there are some that run away, but most stay and fight. I do think that not everyone should be involved, but i mean, they're all prisoners, not like they got anything better to do! They said something about your friendships and other relationships evolving as you interact with your companions in full game.
As for multiplayer, you can either post on here or on steam to find a group, I'm sure you can find story dedicated people.
And I'm sure they can give you advice and talk you through the game if you really do suck that much. xP
