Well as far as mainstream languages, I really can only do C#, C++, Python, and a bit of Visual Basic. If we're counting more niche stuff, I can do GML, Ruby, and Kismet (I personally don't consider Kismet a language, but lots of indie teams want to know if you're experienced with it)
Story and design have always been my forte, so I'm not a fantastic programmer. I pretty much just know enough to get by, and have to learn a lot of it as I go.
