Roguelikes: permadeath, procedural generation and all that

A roguelike is a genre of role-playing video games characterized by certain gameplay elements and mechanics. These games are inspired by the 1980 game "Rogue" which is where the genre gets its name. The defining features of roguelikes include:
Procedural generation: levels, maps, and other game elements are created algorithmically rather than being pre-designed.
Permadeath: when your character dies, you typically lose all progress and must start the game from the beginning. There are no checkpoints or save points to reload from.
Random loot: items, weapons, and equipment found in the game world are often randomly generated.

Roguelikes come in various settings and themes, ranging from traditional fantasy settings to sci-fi, horror, and more. The genre has seen significant evolution over the years, leading to sub-genres like "roguelite" and "roguelike-like" which may have some of the core features of roguelikes but with more forgiving gameplay mechanics or progression systems.
