We use dolphin and play games like Mario Kart, Super Smash Bros, Mario Party and pretty much any other game that sounds fun.
You can download Dolphin Emu https://dolphin-emu.org/download/
Dolphin 4.0.2 is stable but lacks graphical enhancements on certain games
4.0-4652 (dev version) Will run games better but everyone needs it to be able to play online, I recommend getting both.
