Parsely from Memento Mori Theatricks is a fun little RPG that replicates 1980’s text adventure games (adventure, Zork). The GM plays the role of the computer. Each player takes turns giving a one or two word command, and the GM responds just as the computer would. It’s a lot of fun.
Some players (especially younger ones), might not be familiar with those old games, so I’ve made a quick player command PDF that can be handed out. It has a list of common text adventure commands.
