Moria

Like NetHack, Moria is also an early clone of Rogue. However, Moria influenced an entirely different line of Roguelikes than NetHack. ("Hacklike and "Bandlike" are the two lines. Bandlikes are called so because of the major game later in the line.) Moria's main features include: almost everything from rogue and a unique feature: a "Town" level. It released its sourcecode early on, so this roguelike has a great many clones, the greatest of which is known as AngBand. It has many fun features but, however, you may want to just play its clones because they stopped development on this game in the late 1980's.
