When I first set up the PS3 I chose Spanish as a default language (because that's my default language too). But after playing Dead island for a while I decided the punny Spanish names for the trophies I was earning were horrible, so I changed the language setting to English. While every other game I've ever played AFTER the change has earned me trophies in English, Dead Island keeps writing them down in Spanish. What's more, my girlfriend made her own user account in my PS3 and started playing Dead Island herself, and SHE earns her trophies in English. So what the hell, Sony?
Shuckle.
