Are you a big fan of playing games like Cuphead with friends but don't you feel like traveling miles to do so? Then Parsec may just be the solution for you. It allows one (or more) computer(s) to connect to another and the host can give the invitee(s) permission to use his own keyboard & mouse or his controller so they can play local multiplayer games together without the inconvenience of having to be on the same computer, and it's completely free! You can decide what apps your friends can see and control, so when you're having a coffee break they won't be able to search through your computer.
