Does Overwatch, the Blizzard game, count as cyberpunk, or does cyberpunk require a darker aesthetic?
I only know cyberpunk through CDPR’s Cyberpunk 2077 game, and I guess also through the Blade Runner movies. So, I don’t really know much about it from literature or tabletop games.
That said, Overwatch has a lot of the same themes, but with a brighter “Sunday morning cartoon/anime” aesthetic.
Overwatch has a lot of the same sci-fi elements, but I don't think cyberpunk would be an accurate way to describe it. In a way, it's a patchwork of a bunch of different stuff; for example, you might say Sombra is cyberpunk. But I don't think it generalizes well.
One of the main things in cyberpunk (and in a lot of punk genres) is economic inequality and the flaws of capitalism. In Overwatch, large corporations are part of the setting (and so is poverty, I would guess), but that's all they are — background set pieces.
I think it mostly looks futuristic, and not cyberpunk, what I consider cyberpunk look is more dirty, less utopistic and polished look. I tried to post image from Deus Ex Mankind Divided Golem City, but it didn't work for some reason.
