Variety, Social Aspects More Important To Game Success Than Graphics, Plot
proslack writes "In a study presented at the Human-Computer Interaction conference in Cambridge, England, British researchers Beale and Bond found that plot and graphics are not critical to the success of video games; price and the inclusion of social aspects (e.g. multiplayer or chat) were found to be more important."
An unfinished version of the paper (PDF) is available from the researchers' web site. They said, "One of the most unexpected findings was that gameplay was not featured as one of the most important categories to fulfill," though they acknowledge that variety and cohesion were measured separately from gameplay, which past studies have not done.
One of the first multiplayer games we played was 'grid' by Peter S. Langston - it came with a USENIX archive tape. The game itself was an ASCII rendering of 'grid war' in first person perspective, but it supported inter-player communication. Other mainframe multi-user-dungeon games were also popular as they also had the multi-player capability.
