I agree, even though Conviction was kind of my introduction to the series. I was too young to play them before. I remember playing the first Splinter Cell when I was really young and I got stuck, lol. A few years after first playing Conviction, I bought all the games. I've heard people say that the Xbox/PS2 version of Double Agent is on par with Chaos Theory, but that the Xbox 360/PS3 version is worse.
