Lua in particular is gaining a lot of traction in game development these days. It's are suitable for tight inner gaming mechanics, but for scripting events and scenarios it's used by pretty much all the major studios. Love provides the missing part of Lua (the fast routines necessary for game dev), but Love itself is unlikely to be used in a AAA product due to the Lua back end. That said, they're very capable languages and complement eachother very nicely.
