Gamasutra's 'Quantum Leap' awards roll on, with game developers voting in the titles they see as the most important multiplayer titles ever made. These are non-massive multiplayer games that significantly advanced the pastime of playing videogames with other people. Some of the listed games are gimmes (Goldeneye, Tribes), but I thought an Anonymous submitter's comment about humble Pokémon was interesting: "Tajiri-san's introduction of the collect and trade concept opened the eyes of every developer, all of whom previously believed multiplayer was either head-to-head or cooperative. What Pokémon created with this breakthrough concept was a true sense of community centered about a game - a kinship among people which transcended the immediate game environment. With the inclusion of real-world Pokémon merchandise, and a constant flow of new, wicked-cute characters, it was easy for anyone to embrace the Pokémon lifestyle...not that I would ever admit to it." Any multiplayer classics you'd add to the list?
