There could be upcoming, unfinished games that are better (in your taste) then every finished game and you would just boycott them due to this incident.

Well, I'll buy them, when they're done. Indeed, there are a few awesome forever "early access" games, but all of them have an ending, so basically they're complete, just missing some promised features.
But then, some books are unfinished due to the author's death, and they're still classics... From this point of view, maybe it was worth it.
