I am an older gamer and a bit confused!! I've played splinter cell, splinter cell chaos theory, pandora tomorrow and double agent. on my xbox, I have just upgraded to a 360 to play the later games in the series. My questions are, what comes next, I thought it was Essentials then conviction then end war but havn't got a clue, can somebody put me right and tell me what's available, whats to come and the correct order and was essentials available for the xbox or just PSP, sorry for so many questions but please help
thank you in advance from a keen novice

Order goes,

Splinter Cell,
SC: Pandora Tommorrow,
SC: Chaos Theory,
SC: Double Agent,
SC: Essentials (this is a PSP only game)
SC: Conviction (this game is still being made so can't be bought yet).

You might as well get the Xbox360 version of Double Agent as well since it plays a bit differently from the Xbox version. Different missions etc.

End War isn't part of the Splinter Cell series.

Thank you from "now a little less confused"
