Not exactly playing, but learning my way around the GECK to create a few personal radio stations for New Vegas. I've learned how to do most of it, I just now need to sort the audio files and add them. Too cold to sit at my desk and finish this, so I'll do all that later.
(Before anyone says "why not just use the mod that lets you add your own music files", it's because I need separate radio stations with unique names that I can switch between, each with their own chronological order, rather than one giant one which basically works by saying "random bullshit go".)
