Os Loucos de Lisboa (The Lisbon Crazies) was a 3-year (2015-2018) ongoing live-action role-playing and alternate-reality hybrid game, with persistent world-building, usually played in real-life secret or abandoned random locations.
The game was mainly mystery-themed and had a contemporary setting; sessions were played in small (5-10) groups, and prop-based roleplaying was heavily disincentivized, favoring instead psychological and introspective approach from players.

Os Loucos de Lisboa was designed, written, hosted, and game-mastered by Isaque Sanches.
