This is a very polished game - there are a small amount of scripting errors, that's about it. Virtually no broken quests, no crashes, etc. They clearly opted to produce a polished game with plenty of 'depth' in each area instead of a 'large content' game, and there's no reason not to play now if you are interested.
The game should please anyone who liked Age of Decadence, although it's a very different beast, in fact. It will also please anyone who wanted TTON to be good (or, I guess, if you enjoyed TTON). It knocks most games out of the park without hesitation in terms of atmosphere and style.
For me, the closest experience is actually the way I play P&P - the feeling of saying 'alright, I'm going to play a cop who's been beaten up one too many times by life and now decides to weather the storm through florid performances of SUPERSTAR coloured by disco nostalgia', then finding all the skills and choices that support this, seeing the entire game shaped through that, and then, the game throwing me enough new information, choices, emotional moments, where said character goes through some kind of change - perhaps to a more sombre man who begins to accept his failures, perhaps to a paranoid apocalypse obsessed cop, etc.
It is pretty great.
