searching an island game 8-)

hi folks!!! I already heard that there was a game you were alone on an island and you can do anything you want. i don't know how to explain it but it seem to be a game of a a real person who live the day, the night, play fun games, I think it's in the style of lost in the blue. I search this games everywhere but didn't find it... Did I dream it?:P

Thanks!!:D
