Outline of Oangband Features:

- The elimination of years of slow HP and damage inflation, and a "tabula rasa"
approach to game balance in general.

- A fundamentally altered conception of physical combat.

- A radically revised magical system, offering you the chance to play any of
four spellcasters, any of four warrior-spellcasters, or the pure warrior we
all know and love.

- Very much more varied classes.  Mages are great with magical items, Rogues
steal and set traps, Assassins whip poisoned knives at their foes, Paladins
smite with elemental powers, Priests evoke the power of Holy Light, and
Necromancers just blast everything in sight.

- Races are also more differentiated.  There are three new races, including
one designed especially for new players.

- More ways to combat monsters.  Now you really can start and win the game
relying on magic, melee, shooting, throwing, or magical devices to do damage
to your foes.

- The most cunning AI in any Angband variant.  Monster mana.  All sorts of new
monster nastiness.  Dragons are dangerous once more, Undead have a deadly touch,
Trolls will gleefully pelt you to death with boulders, and those Zephyr Hounds
are out of control.  In Oangband, even the snakes have attitude.

- Enhanced object description and learning code.  Dungeon features that affect
movement, sighting, and combat.  Exciting chests and nasty traps.

- More varied dungeons, including new room types, special levels, lakes, forests,
and lots of new vaults.

- Shapeshifting, interface enhancements (including big-screen), and circular
detection spells.

- One-slot wand and rod stacking, arc spells, themed random artifacts, and
player ghosts that challenge you to mortal combat.

- A versatile quiver that makes archery really practical.

- New just about everything.  Whether it be Wands of Storms, the Dark Elven
Smith Eol, Shields of Night and Day, Athelas, Amulets of the Lion, Large
Jeweled Chests, or activatable rings, Oangband has novelty enough for anyone.

- And Angband-compatible savefiles.

This list is very skeletal.  If you desire more detail, read the on-line help 
docs, consult the various version diffs files on this website, or even consult 
the code itself.
