Arcade machines are awesome, but it's not really feasible for most of us to keep one in our house. If you're looking for something a little smaller, Instructables user Rolfebox shows off how to build a small tabletop machine built for two people.
The process here is pretty intense and will require some basic woodworking and electronics skills. You'll be building this sucker entirely from scratch, including the buttons and casing for the machine, so prepare yourself for a bit of work. The machine itself is powered by a Raspberry Pi, so at least that part is pretty easy. Head over to Instructables for the full guide.
