I agree with everything you have said here.
For me what comes very near the top of the list though is ‘transparency’, ‘honesty’ and ‘good communication’.
I am often happy to buy an early access game as long as the developer sells the game as just that and not a full blown final product. I then gamble on its final outcome with full knowledge. That is okay for me.
What really is unacceptable though is when a game is launched as a full product and it is really an ‘alpha’ or ‘beta’ and the developer determines to fix it over the coming months or years. You then have to wonder if this was the mind set all along rather than just things not going to plan. I am talking here of serious game bugs and not minor bugs which could be viewed as irritations.
This sort of dishonesty leads to distrust and negativity. Never a great start to a new venture since all that trust then has to be gained again which is no easy task. It is also very disappointing too and not what most of us want
