^ I'm shocked you left out the BEST game series
on X-box; Fable!
There's the original Fable and the Fable: Lost Chapters that were released for the regular X-box, the Lost Chapters is basically just an extention of the original Fable game, so I would skip the original and go straigth for that one, it has one more land an additional story quest and several side-quests.
Then there's Fable II and Fable III that were released for the X-box 360, which both have a much bigger world to play in, more features and options. Fable II had a poorer story, but still was a decent game, while Fable III had a decent story. Fable:TLC is the best one, followed by Fable3 and then Fable2.

What I love about these games are the way you shape your character by the choices you make as a player. You can do "good" deeds, "evil" deeds or a little bit of both and remain "neutral". You can "train" your character in strength, magic or skill, you "dress" your character to impress, invoke fear, attract people, repulse people... there's so many options. You can stick to the story, you can do side-quests, you can take a partner, in later games you can have family...
I also love the Buffy-games on X-box, but that might have something to do with me being a fan of the show
