Lenna’s Inception
There was quite a bit of interest in Becky Lavender’s research into procedurally generating Legend of Zelda dungeons, but did you know that there’s a procedurally-generated game in the style of Legend of Zelda that you can play right now?
Lenna’s Inception is in early access, but it’s already got a completely procedurally generated map, generated dungeons, procedurally-hidden treasures, side quests, an unidentified potion system, and more.
The game currently has a Gameboy-ish graphics style, though a more colorful updated graphics mode is also in the works.
Despite its not-yet-finished state, there’s a lot of solid use of procedural generation already implemented, and Tom Coxon, the main developer, has talked extensively about the map generation and lock-and-key system the game uses to make the entire overworld and all the dungeons procedurally generated.
