omega is a complex rogue-style game of dungeon exploration.  Unlike
other such games, there are a number of ways to "win", depending on
various actions taken during play. The ways you can get your name on
the hiscore board include becoming the highest ranked head of a guild,
sect, college, etc., as well as gaining the most points figured from
possessions and experience. The game (via the oracle) may impose some
structure on your exploration, but you need not follow all of the
oracle's advice. There *is* a "total winner" status, by the way.

omega offers a richness of playing detail that goes beyond a simple
game like rogue. However, the majority of gameplay is very similar to
rogue, hack, ultrarogue, larn, and other such games. The player is
represented by the highlighted "@" symbol, objects and terrain
features are represented by non-alphabetic symbols, monsters are
represented by the various upper and lower case letters, and other
humans are represented by a non-highlighted "@". It is recommended
that the novice read the man pages for rogue or some other such game
and perhaps play a few games before playing omega.
