I usually play in Skirmish mode, but I don't like nukes. Unfortunately, you can't disable them in single-player Skirmish mode. So what I used to do in Windows was to host my own TCP/IP game, add an AI player, disable nukes, and then play. Unfortunately with Crossover Games 9.2.0, TA goes back to the main Multiplayer page when I try to host a TCP/IP or any other type of multi player game.
