My favorite from those times was Splinter Cell: Chaos Theory. I’ll never forget the 2 v 2 Spies vs. Mercs. First time I experienced Proximity Chat. The spies could sneak up behind you and once they were near, they could whisper in your ear, so you’d get a lot of, “Hey, baby…” and other funny stuff before your neck was snapped. It was so much fun and I still wish for a replacement.
