I tend to be a little embarrassed by games when they start swearing too much (talking more than your average R-rated movie) or show non-tongue-in-cheek ultra violence for pretty much no reason. Makes games that are supposed to be for adults seem childish and immature instead.
Splinter Cell Conviction. Good lord that game was jeuvanile with its swearing. I don't mind swearing in a video game, I'm not a prude, but the henchmen in that game were swearing like pre-teens on Live.
