That was my reaction too. I thought at first it was a game for 5-year-olds until I saw the enthusiastic replies of other adults on the thread.
To each their own but video games in general are loud and give me a headache. When I was much younger, I would go to the arcades with a pocket of quarters and play Pac-Man or Space Invaders. As a kid, I would bang away on those pinball machines.
When computers were relatively new, I did some Wolfenstein 3-D and I believe Doom but that eventually bored me and I never went back to playing the video games. However, I do play simulated blackjack once in a while if that is considered a video-game.
But if other Freepers like these sort of games, I'm not going to condemn them for it even though personally, I would not want them in my house because of the aforementioned noise and headache-inducing graphics. I'd rather put on some music, open a good book, pour a glass of wine and sit by the fireplace.
It’s an extremely difficult game with design paying tribute to late-1920s-to-1930s cartoons and includes some of the dark humor many cartoons of that era had. IOW, while it is colorful, Cuphead is aimed more at adults than kids.
