Akalabeth: World of Doom

This is the first and initial game of the Ultima series (having 0 index), and also the first game for the fourth generation computers. Akalabeth was produced as an independent game and it got its index number of the Ultima series only in several years, when several games having Ultima name were produced. Akalabeth is recognized as one of the earliest known samples of the computer role playing games (though initially it was pure amateur project)
