I enjoyed XCOM:EU's tutorial, it was cinematic and taught me what I needed to know without patronising me or making me feel frustrated or bored.
Mass Effect 2 and to an extent 3, due to my investment in my Shepard and his galactic ass kicking crew, I immediately hated the Collectors (which was the point I guess) and wanted my team back from the moment Shep woke up again.
Halo 3 is up there, mainly because of how excited I was and the 1st mission is classic, fun Halo combat. Love it. (plus 1st game I played in HD)
Honorable mentions go to Half Life 2, Dishonored, Borderlands 2, Skyrim/Oblivion and GTA IV
