What I tried to do was start a LAN game, and have him join. He is NOT ON MY LAN. So maybe it would work for other people, but not me, even though I opened up the port. So, if I start a server, could I do what I want with it? Or are the servers that you linked me to just an auto-run game that I can't add any bots to?
My friend and I like to play together in a game that we can change the settings in, like addbot, and all of the gravity settings and stuff. That's all we're trying to do. Is there a way that won't be too laggy? Because I know that I tried to get a server running for CS 1.6, but that was horrible...
