Secondly the dialogues are hardcoded anyway, the story is still driven by the main character, the control of the DK is only there to make the game, mainly the combat more fun.
This is exactly why it works for hack'n'slashers like BG:DA but *not* for story-rich real RPGs with meaningful dialogue, in my opinion. The 2nd player gets to tag along, not participating in the dialogue, merely a lackey. Why not play one of the games that is well designed for this sort of play (BG:DA etc) rather than trying to force it onto a game like BD that is as much about story and dialogue as combat?
