Hi, if some one here plays halo 2 on xbox live and knows how to host games under opti match, then could you please tell me how. I realize that most of the opti match games are just randomly made by A.I. but i have the official stratigy guide and it says that it can be done. But it doesn't really tell you howw to do it. i've asked about 15 people on xbox live but they all tell me to just creat a party but then only people on my friends list can come to it or people that i invite. I want to know how to host under opti match so if you know could you please tell me how
