Games can't be emphasized enough. Grim Fandango and Escape from Monkey Island in the late 90's were the first known corporate games that used Lua. After word got out at GDC, the entire industry started using Lua. Big profile hits like World of Warcraft and Angry Birds make Lua sound like something new in the video game industry, but Lua was already de-facto standard. If you buy a game today, there is a greater chance that it uses Lua than it not.
