is to have him fight Loghain one on one - by that point, Al is badass. It seems very fitting, and he dispatches Loghain like a warrior should. I cannot see any reason to let Loghain live after he abandoned his king, his best friend's son, his daughter's husband, on the field at Ostagar. None of the reasons the ardent Loghain supporters have come up with about "why" he did that take away the fact that this supposedly amazing war leader quit the field. If he was so intelligent and supporting of the crown, he would not have needed to wait for the signal fire anyway... And then he grabs the regency - why? If Anora was fit to rule, she was certainly of age not to need her father as regent. Heh - sorry, I feel like the writers really flubbed the whole ending triangle there, with trying to basically retcon Loghain in order to allow an "ending" that doesn't really gibe well with the story they were telling. Having Alistair run off in a snit does such a disservice to what may arguably be the best developed character in the game. It breaks his character, basically, which was really disappointing. And which is why Loghain always gets offed in my games.

Is there any way to make Loghain a warden and not have Alistair become a drunk/leave, its tricky because I didnt harden Alistair, I felt like the dialouge to do it would be pretty harsh. So is this possible or is it one or the other ?

You can never have both Loghain and Alistair, and the only way you can have Al live past the Landsmeet without becoming a drunk (or executed) is to convince he and Anora to marry. And he'll only agree to that if hardened.
