Yeah, this presentation by Roberto Ierusalimschy (one of Lua's three authors) lists over 50 games that use Lua (slide #9):

I am surprised that he did not include all of the Souls games, as they are hugely popular.

Oddly enough, I learned that they used Lua by reading the license information which came with the game. I don't remember if it was on the back of the box or in an paper insert, but it surprised me to see it included for some reason.
