I just finished the single player campaign for Splinter Cell: Conviction and really enjoyed it. Just like in Batman: Arkham Asylum a real sense of empowerment is instilled in the player, something that previous entries in the series lacked.  Throughout the game you feel that hidden within the shadows you are the hunter, even when coming up against enemies with some of the same fancy electronics Sam posses. The last known position system makes letting the enemy see you just so you can flank them and snap their necks with a melee kill great fun. All this makes for a great time, just make sure you play on realistic as even on this setting it was a bit on the easy side.
