Even then they should still be held to a higher standard.
Especially now in the era of generative AI.
The poster should have a well known character in the world lore holding the Coke, or a location in the map for the car ad, etc.
The ads should feel like they are actually a part of the world, and shouldn’t be put in a game unless this can be accomplished.
In game ads don’t have to suck. But because the power dynamic is such that shit ads can be shoved down players’ throats with the only response being to not buy that publisher’s games, the medium isn’t going to find an acceptable equilibrium.
In game ads in live service games for in game assets may not suck too much though (an inevitable part of the future).
