What I'm really enjoying about Splinter Cell: Blacklist is the consequences of violence. Being loud and fatal is a disadvantage to sneaky, non-lethal and even undetected. You get a higher score the more non-violent you get. The highest points come from levying "enemies" untouched.
As an amendment to the recent discussion on FriendFeed about USB plugs etc, I just troubleshooted a USB harddrive issue for a person in the office next door. "I plug it in both ways and nothing". Walked over to their office, looked the the laptop. They had plugged the USB cord into the LAN port.
