Will old consoles like Gameboys still be worth it in 2021?

Compared to the Nintendo switch?

It depends on whether you want one. I'm very happy with my Gameboy and there's always a bit of nostalgia with it. Lg

It depends. It's worth it as a collector. In general, I would choose the switch because you can also connect it to the TV. At Nintendo it is only worth buying the old consoles to have them in the collection, or you buy the old consoles because of the exclusive titles that were only released for the console.
