This is a mistaken claim. Naughty Dog, for example, uses a precompilation phase in their games involving Lisp that builds into machine and graphics code. Most games, too, have a dynamic runtime in the form of a customized scripting engine in their game, tailored to the needs of their game. Sometimes this is done with a pre-existing language like Lua, sometimes it's built from scratch, like UnrealScript (Unreal1 - 3 engines). All of these are now banned.
