Thinking about the Game & Watch games, a lot of them have silly premises. Many video games are built upon silly premises like driving a jumping car on platforms, but the most important thing to note about Game & Watch is that it was one of the older video games, so it not adhering to what made sense might have stand out in the midst of more serious and grounded ones, like ones about shooting aliens in space, or maybe a frog travelling across the street to the other side.
Quite a few are more mundane and grounded, like how Ball is just some guy juggling multiple balls to keep them in the air, or how Boxing is merely two boxers punching each other until one is knocked past their side (now that I think about it, Boxing G&W and Urban Champion have a common DNA). And then you have things like Turtle Bridge, where someone must travel through a row of turtles to deliver packages from one end to the other, or how in Rain Shower, the person somehow thinks it's better to leave the clothes dry and then hop through the clotheslines to prevent raindrops from wetting the clothes. Even established characters aren't exempt, because there's Donkey Kong 3 where Stanley and classic Donkey Kong shoots bug spray to make an insect sting the other, or notably Mario's Bombs Away, where Mario must take a bomb to the other side to his comrade, who is inconvenienced by opposing soldiers and even a (presumably friendly and unaware) comrade callously throwing matches on gasoline.
Even then, I think there is something to be said how all these silliness don't matter, because those games are fun. Like it would seem more inconvenient for the Mario Bros. to endlessly move boxes through conveyor belts, but there is a fun challenge to be had while doing it. In fact, I kind of wonder what sort of Game & Watch might have been made now, if one may come once in a while, maybe if Nintendo decides to make another Game & Watch and add a new sort of game instead of a re-skinned one (reskinned are like Mario characters in Ball, and Link in Vermin)?.
Thank you for reading.
