So general solutions are welcome, but a friend and I are both craving the old blizzard RTS games. The problem is: fuck that company, and they probably use a rootkit anti-cheat anyway
So is there a general solution for multiplayer in old PC games without company support, and is there a particular solution for, say, starcraft2?


If those games can do LAN connections (computers on the same network), you could use something like Hamachi to put your computers on a virtual network together. I’m sure there are more modern versions of Hamachi, but that’s how I used to do it in the early 2010s.
Tailscale is the one I use. It’s free for up to 5 devices.
Had problems with hamachi but Zerotier works great. Less hassle also.
