Games journos and streamers, where a majority of purchasing decisions comes from these days, don't finish games. They play the first few hours and then that's where the majority of people make the decision to go buy it or not. Games journos will never revisit it, and the streamer probably won't either (and if they do it'll be stretched out over weeks to give patches like this time to happen).

So from a pure soulless business perspective, its absolutely valid to rush out a game that's got a functional first half and then spend the next few weeks/months after its "gone gold" and released finishing it up. Especially as the majority of players will only play a few hours per week, so you theoretically have time to get things finished before they reach the bad parts.

Its not a great setup for all the obvious reasons, but that is what happens when Corporations enter a hobby industry. They treat it as a numbers game with retarded standards like that.
