But in all seriousness I don't think you can define most video games graphics as being intentionally one or the other - I mean...I think anyway.
I very much disagree, there's A LOT of stylisation in games in general. An example off the top of my head would be Zelda games. I don't recall if many of them were graphically impressive in their time, but most of the 3D ones either didn't age well or looked old already at release... from a technical point of view anyway. Because many are very stylised and beautiful in the "artistic" sense; art direction does the heavy lifting here and makes up for a game being lacking in "modern graphics". BotW hardly has "cutting-edge graphics", but it can look amazing.
I mean it mostly in a very general sense, as in disagreeing with "graphics in game not intentional", but very specific stylisation (art direction based on a specific artist or style) isn't that rare either. Or perhaps you meant something else entirely.
I mean did the Art Director intentionally set out to create an Impressionist style or a realist style, or do you mean of all the possible styles that Art Directors aim for one and hope the budget covers it?
Probably not Abstract that I can think of, but Modern definitely, also Contemporary and Surrealism.
