In a surprise move, Atari has released a time-crippled "demo" version of Greyhawk: The Temple of Elemental Evil, offering you to play up to six hours of this recently released Dungeons & Dragons 3rd edition RPG, developed by Troika Games. The reason for this massive download is that after purchasing a key online for $49,95, the game converts itself into the full version - with no further downloads needed.
