True, but that does not negate the fact that they over promised and under delivered. Doubtless thanks to this unethical tactic they have generated many more sales than if they were more conservative with their expectations. They advertised a game that would be the new gold standard. Instead they provided a buggy status quo.
The two particular videos themselves didn't over promised - in fact they were transparent and clearly stated that it is subject to change. And it was changed at the end. Guess who is responsible for hyping themselves up before actually seeing the real product yet? I think we both know the answer to that.
Imagine someone who didn't actually follow any of the "promises" over the years. Do you think they would actually feel "lied" to that there are "missing" features in the game?
