1 - The pinnacle of independant game creation.
2 - The best game one can possibly create.
The term originated in an Internet community of game designers who worked with the OHRRPGCE. A "Do-More-With-Less", time-limited game creation contest produced only two results, both of which were so poor that it prompted one of the members(named Gilbert), to vote for a 3rd imaginary game, entitled Airship 2600. The game proceeded to garner more votes than either of the other games and unofficially won the contest.
Your graphics are good, but they will never be as good as Airship 2600's.
