I'm trying to get some old strategy games working so i can play them with my brother. He's highly autistic, and as a result he has a real fear of the internet. I was hoping to play some games with him over LAN, so we could avoid connecting him to the internet. If there's only two of us is it possible to just run an Ethernet cable between our computers or will we need a switch, even for only the two of us. If we need a switch would it be possible to use an old router (we have some lying around at home)
Sorry for the basic question, networking isn't really my wheelhouse
Cheers
