I'll preface by saying that I think we are operating on different definitions of what we mean by 'marketing'; I'm not sure what your definition is, but I'm using the general one – everything by which information about the game is pushed, shared or presented with the goal of generating interest that could potentially lead to sales, is advertising and marketing. I feel as though you are using the word 'just' to refer to the extreme end of sensationalist splash media? That may be our disconnect.
At any rate... It's a nice and fluffy-sounding ideal, to say that you are unaffected by marketing.... but it's false. It's unequivocally false, and if you believe otherwise then you are deceiving yourself. You do not buy games with your eyes closed, picking them up blindly and at random off shelves; however you inform your decision, it is through the game's extended advertising and marketing that you do so. Otherwise you do not know that it exists at all.
I looked at it and went; "Wow, this game looks amazing. I want to play it".
Congratulations, you were affected by advertising and marketing. That is the very definition of being so.
How do you come by the gameplay footage that you review before deciding whether to play a game or not? How do you decide
which games to check or view gameplay footage of in the first place? Doesn't matter what your answer is – it's a result of marketing and advertisement of the product.

The more problematic question that this led me to, and I apologise for going as far off track as I am right now... is this:
Is it the case that, because you use a very specific narrow lens to base your decisions upon (direct gameplay footage), you literally do not care if developers and companies use the breadth of their other advertising tools (which you personally do not look at) to claim that their product is or will be a number of things which it ultimately is not, and in some cases never intended to be? Are you saying that you don't care, would still support the company if they made a game you found fun, and would think that that behaviour is completely acceptable, just because it didn't happen to affect
you – that is, because they didn't lie to
your lens of decision-making.
What about if they advertise 'raw gameplay footage' that grabs your attention and you like the way it looks, and so buy the game... but when you get it home and start it up, it's actually nothing like that at all, and the 'gameplay footage' they showed you before isn't even in the game... this has happened in a couple of large cases not too long ago, in fact. Lots of folks were very unhappy, to say the least. Such a circumstance would put you in with the other folks who look at more than one metric when deciding whether to buy a game; would you still think that fair and acceptable? Would you still be happy and content with the game, if they lied to
your lens of decision-making, as well as the ones others use to inform themselves?
It comes across, the way you worded much of what you said, as though you feel that it's perfectly okay for developers to misrepresent, mislead, deceive or over-exaggerate what they are producing and selling, to other people's lenses of decision-making... as long as they don't do it with yours.
I do not look at Baldur's Gate 3 and go; "Oh... Baldur's Gate cRPG. Well that must mean 20 companions, no chain system, no surface attacks, every choice matters, grim serious atmosphere, no talking squirrels, real time with pause, day/night cycle, unlimited party size, proper reactions, proper DnD systems, math calculations, no origin characters and so on whatever is promised or not promised.".
Nor do I, but:
When they say: “We're making the a game using the 5e D&D rules” - I expect them to make a game using the 5e D&D rules.
When they say: “This is going to be the definitive example of 5e D&D in a video game!” - I expect them to make a game that uses the 5e D&D rules to a reasonable level of fidelity and faithfulness, without large scale or excessive deviations to the core system, and I expect that system to be as feature complete as is reasonable.
I'm a simple woman: when I hear a game developer tell me what sort of game they are making, and what will be in it, I have a tendency to take them at their word and assume that they are not deliberately lying or misleading me – that they intend to do as they say. I grow dissatisfied and unhappy when they don't, because I do not appreciate being lied to or misled, especially when it results in a product that I might not have chosen to spend money on, had they spoken more honestly.
