You can get older ones even like the pi 3,4 for cheap, but they don't play gamecube, Wii etc very well. Be warned they use a Linux os, which you need to load onto a micro SD card yourself. You can find pre built images like "retro-pie" online free tho which makes it easy to setup.
Why would you want to use a service you can't run your own servers for and that likes to play censor?
