This is the second game I've found out recently that is written in Lua. The first one one being - Beyond All Reason.

Beyond All Reason is a SpringTA fork (hack? build?) like Zero-K? So the underlying engine isn't Lua, but higher level scripting is. I'm pretty sure this is fairly common, or was once.

Other games with Lua scripting: Roblox, Baldur's Gate, Civilization VI, Crysis, Factorio, World of Warcraft, Far Cry, Leadwerks, Friday Night Funkin', Foldit, Garry's Mod, Aquaria, Balanced Annihilation, Bitfighter, Bos Wars, Cataclysm, CivCity: Rome, Civilization: Beyond Earth, Company of Heroes, Cortex Command, Counter-Strike 2D, Crimson Steam Pirates, Dota 2, Dungeon Crawl: Stone Soup, Dungeons, Dungeons II, Dungeons III, Elven Legacy, Empire: Total War, Escape from Monkey Island, Eufloria, Exodus from the Earth, Angry Birds.

Recently released, Moonring and Balatro are both written in Lua, and I think both with LÖVE.

Lua is traditionally the scripting language of choice for game development. It was absolutely ubiquitous in the industry before the days of Unreal/Unity. Famously, all of the WoW UI was Lua.

YOYOZO, my game that received a "Best Games of 2023" accolade, was also written in Lua. It is only 39KB despite containing two music tracks, physics and particle systems, online high score board, dynamic sounds, two fonts, a tutorial and more. https://news.ycombinator.com/item?id=38372936

LOVE is a popular Lua game framework, so quite a few indie games are written in it.

Most of Heroes of Newerth's in-game logic is written in Lua.

Grim fandango too
