You can use an emulator to enable your device to run software that was designed for a different system. Using an emulator, you can for example run a DS game on your smartphone. (Don't ask me about the legality of emulators)

Emulators are also often used to play fan games (for example p*kem*n fan games).

There are also programs such as Bluestacks that allow you to emulate an android device.

Basically giving you the ability to play any Play Store app on a PC.

I do not endorse what I'm about to say next. I just pointing out a flaw.

Recently, one game that's been really popular is Among Us. The PC version costs a small amount, however the mobile version is free. Both versions are basically identical and cross play is available.

Of course, if you enjoy the game, do purchase it to support the creators.
