Hello there, I just got a little Idea that could be nice for the… “imersion”, I think.
Why not put some sort of radio in the garage, with more musics for the player to listen while developing game, and why not make a better action game while listening to metal or hardcore music ?
Or listening to some classical music when developping an RPG, for being in the mood, you know ? And this way make better games with the good music for the “inspiration” 
And then, in the second office, why not have sometimes some troubles with others employees that don’t like the music in the office ?
I think we could go a little bit deeper with this idea, and I hope you will !
(Oh and don’t worry, the music of the game is pretty cool ^^)
