Unlike any other game I've played on this site, "Mystery Case Files: 13th Skull" combines the hidden-object gameplay with live action human characters and real backgrounds. The player feels like he or she is actually inside the story, taking part in solving a well-devised mystery. Full of twists and turns, a highly atmospheric setting, realistic sound-effects and mental challenges galore, this is arguably the best game on the site. I've played consistently for just over a year, and have yet to find another game to match the quality of this one. I was kept guessing about several major points (including the outcome) right to the end. Like a really good movie, it stays with you - and for a game of this type, that is extraordinary.
