*** PLAY SOLO OR IN A GROUP WITHOUT A DM *** Endless RPG is also available for mobile platforms, but on Windows you get the benefits of a big screen. The tool can even be used for running full campaigns as an easy way to fill a tower with gobins or some ruins with the undead. It is is a tool for playing D&D 5e alone, in a small group without a dungeon master, or with a dungeon master as either a standalone adventure or an easy way to get into the game.
The Random Dungeon Generator is not a game. Endless RPG is a random dungeon and map generator for 5th Edition Dungeons and Dragons.
