Like a couple of the games before it, 13th Skull blends well illustrated backgrounds with live action people to make a pretty convincing scene in which you can test your detective skills. That being said, the acting that portrays the characters you are interacting with feels very wooden, and at times, over the top. Actually, it felt a lot like participating in one of those mystery dinner theaters where you ask the cast questions and they reveal their part of the story to you. I don't know if it was the directing, editing, or just generally wooden acting, but the character interaction definitely doesn't feel natural.
To top it off, I actually felt a little insulted at times since the game takes place in southern Louisiana and a few of the characters portraying locals seemed a bit too stereotypical for my liking. Of course, that's just because I'm born and raised in the area being portrayed and I tend to get a bit overly sensitive on the matter.
