I am not sure anyone bought HIOI4 in the expectation that it was a 'work in progress'. At best you expect teething problems and issues that may have failed to come up in playtesting. I think Dalwin pointed out that it was a year behind schedule on launch. Which leaves the impression that PDX shoved it out knowing it was unready because the alternative was abandoning the project for lack of resources.
The problem is you cannot really utilise that as a marketing slogan: 'It does not work properly but it is the best we can do on the money for now' is not going to shift many units. So, we are where we are with a game that does not live up to it's billing and the constant refrain that the developers lack the resources to tackle the issues any faster than they are.

Oh, there are ways to market a game that still has many missing features and lots of fundamentally broken mechanics. It's calling selling the game as an early access tittle.
