I'm with Stabbey and LordCrash. A real ETA on AI personalities would be ideal. Some of you are willing to consider this a complete game without them but I will have to hold back and wait until the personalities are patched in. I don't have the luck of being able to consistently play with someone else, (And even if I did I'd end up playing a lot while they were offline and they'd end up lost in the sauce) and I bought this game under the impression I would be playing the role of one character, not two. Especially if I have to decide whether or not something is worth making the two characters argue over it.
I'm extremely tempted to play the moment the game downloads on steam but I know that if I do I will be disappointed, so I may as well wait...
