Yeah, it would bemeganmeave said:I don't know if it's done on purpose or not, but I like it. I liked the soundtrack all through the game though.
Personally I think if you were creating a sound for post apocalyptia, you would probably include elements like this. These people might not know how to properly tune a guitar, if they grew up after the war. Or as someone already mentioned, they could be using scraps they find around. Maybe pig gut would be harder to tune?
The reason it sounds weird to my ears though is that the soundtrack is very highly polished and produced... the guitars are edited and have tonnes of digital effects on them so it really stands out when a part of it sounds musically out of tune.
