I was addicted to the Splinter Cell games from the start. Currently between vomits, coughs, and noseblows, I'm playing the latest title, Chaos Theory. All 3 games out so far pretty much focus on high tech terrorism, hacking, and government espionage. You know, Tom Clancy stuff to the bone.
I need to check out the book, I haven't done that yet. I also can't wait to see the movie.
