Sometimes I boot Gotham Knights just to enjoy the background ambience of Gotham at night while I'm doing other stuff. It's nice hearing the occasional quip from an NPC as something happens down on the streets below, paired with the gentle drumming of the incessant rain. If you scale up high enough, all you'll hear is the rain and the gentle thrum of the city. It's quite meditative in a way.
Sometimes, I leave it running and forget it's the game and not a similar ambient sound on YouTube. I don't even think to check sometimes. I just leave my word processor in fullscreen mode and go about my tasks like a Roomba bumping into things and wandering off to do others.
All of this is to say I just about pissed myself when, after forty minutes of uninterrupted writing and listening to what I thought was YouTube, I went down into the dimly lit basement to do laundry with my noise-canceling headset on, only to get halfway through loading the washer when I heard the dulcet, expressive tones of Jason Todd sighing directly into my ear like gravel sliding over sheet metal.
When I tell you, the scream I screamt. Hgjkgolwmeoihgksdjvmn
Like I'm so sorry, Mister Todd. I'm so sorry. I didn't mean to leave you up there in the rain, but also CAN YOU NOT?!
