A game attempting to pull itself off as an
RPG, but has little more in common other than the fact that there are monsters which have
hit points that need to be
disposed of as quickly and effeciently as possible. Obtaining gold,
experience points, treasure, and other
goodies such as cool-looking
swords are highlights of a hack and slash.
A very popular and great genre if one is so inclined, NetHack is a perfect example of a hack and slash RPG.
