Title: Referent Under Copyright: 'All your nostalgia are belong to us' Abstract: U.S. copyright law extends protection for corporate works up to 95 years after publication. Pong was released in 1972. The first video gaming console, the Atari 2600, was released in 1978. The math is straightforward; any genre dependant on the medium of video games likely finds its entire body of work under corporate lock and key -- with even the most venerable of subjects protected for another sixty-plus years! Nostalgic homage must be corporately sanctioned homage. Plots, character types, even signature behaviors are legally guarded. How is this copyright control wielded, and how does it influence expression? One such pressure is found in the story of the Generations modification for id software's Quake II, a well-reviewed, freely downloadable, third party add-on conceived as a tribute to id's earlier games, but killed by id at version 0.98. Another example is the wholly unlicensed yet legal use of retro-pastiche, as in the Commodore 64 style load screens of Rockstar's Grand Theft Auto 3:Vice City. The third views the middle ground of 'fossilized Easter eggs', or games with esoterically accessible but officially unsanctioned portions, as in BattleZone 2000 (Atari Lynx), San Francisco Rush (N64), Tomb Raider: The Last Revelation, even the Game Boy Dual Screen hardware. Finally, the Atari 2600 'homebrew' scene is studied, where hobbyists operating illegally later partner with Activision to provide resources the copyright holder had long since lost. Each mode of expression -- and the pressures producing each -- help define the practical limitations of a genre closed by copyright.
