Well, you don't have to create virtual limitations. You can also work within real ones by coding for long since discontinued video game systems. The homebrew scenes for home computers like the Amiga and ZX Spectrum, and consoles like the NES and Game Boy are still going strong now.
Working on a game for those systems can be an interesting look into how development worked back in the 80s and 90s, and really test what limits you can push these systems to.
There's also the ROM hacking and modding scenes for old games as well. Whether its console games like Super Mario World or Sonic the Hedgehog or PC games like Doom, there's some insanely impressive stuff being coded for mods these days.
