Two of my favorite games that I enjoyed Single, and multiplayer wise, Were Custom Robo, for the Gamecube. And Phantom Dust, a classic Xbox title. I didnt play either online, (Not like GC had an online system) But even with Friends, the games were simple enough to just pick up and play, with a little Strategy sprinkled in. And, when not goofing off with My friends, both Storylines for each game, were deep and immersive.
