I recently played through Transistor and it was a pretty cool game but one thing I just couldn't get enough of was the terminal opening sound. It feels nostalgic but I can't quite put my finger on what it's reminding me of. It's like part THX logo sound, part old video game sound. Below is a link to the thing I'm talking about (the levels on the upload is a bit low)
I've also been playing Chibi-Robo for the GC and the voice work is all gibberish but there is a thank you noise with an echo that gives me so much pleasure. I've marked it on the video but if it's not, it's at 2:48.
Death Stranding had tons of pleasurable sounds, maybe too many to list.
Are there sounds in games you just can't get enough of? What do you think are some of the most pleasurable sounds in gaming?
