Sometimes spelled "HoMaM", it's the acronym for "Heroes of Might and Magic", a long-lived series of turn-based strategy video game.
The game is set in a medieval-fantasy setting, and allows the player to acquire and manage resourses, build and upgrade structures, recruit units (mainly
mythical creatures), cast spells, explore the world, and lead a "Hero" to battle against other players (either AI or human).
First released in 1995, the game had a number of sequels, spinoffs and expansions, both official and fan-created, the last being HOMAM6, released in 2011. The game changed through the years, however always remaining turn-based.
One of the main features is the
possibility to choose a leading character (called "Hero") from two types of heroes: either "battle oriented" or "magic oriented", hence
the name of the game.
