My pick would be ummmm Halo 1 and 2 it set the standards for mutiplayer with friends at home and mutiplayer online. I'll say it im biased towards FPS mutiplayer games, there my type of ganre.
I'm going to assume you're asking for favorite games so here they are, in no particular order: -The Legend of Zelda: Ocarina of Time/Majora's Mask/Link to the Past -Final Fantasy 1, 4 and 6 -Chrono Trigger -Star Wars: Knights of the Old Republic -Fallout 1 & 2 -Super Metroid
(There's probably more that I could add, but off the top of my head those are the ones that are most important to me)
