Thanks for letting us know
Seconding Stabbey's important question: How many companions are planned and how many are in at release?
I don't doubt that many, if not most people would consider the game complete enough to want to play ASAP, though personally I will wait for the AI personalities. I have looked forward to those since the kickstarter as a core feature of the single-player experience; it is imo the feature that makes the co-operative dialogue system so special in single-player, and reminiscent of P&P gaming with friends (especially because sometimes friends act like they have artificial intelligence ;-)
I have read people saying it is also fun to roleplay both protagonists but I'll save that for potential future playthroughs. I want my first one to be single player and as special as possible - I have been avoiding the beta and spoilers with an iron discipline to make it so. An RPG like this one comes along... well I have never looked forward to a game so much so I will wait.
I don't mind waiting and make no judgements about development priorities or anything as I am not in a position to make an informed one (ie I have no idea what caused them to miss release).
That Murphy sure gets around, I know him well
p.s. This has done little to reduce my near critical mass levels of hype and excitement for this amazing game. The editor stream almost broke my resolve...
