## Context and limits

A wide author's map of classic turn-based roguelikes, modern roguelites and hybrids. Families describe options for organizing a run, and not mandatory features of the genre. Constant metaprogression is not found in all roguelikes. Related systems can be combined; the list is not a closed standard.
