good Xbox 360 game that has a lot of unlockables?

I'm looking for a game with lots of unlockables, something that will keep me occupied a while. Something like Super Smash Bros but for Xbox 360.

Oh, and keep in mind that I don't have Xbox Live and that achievements aren't the unlockables I'm talking about.

About a week later the housekeeper came to the priest and said, "Father, ever since the new assistant came for dinner I have not been able to find the beautiful silver gravy ladle. You don't suppose he took it, do you?" The priest said, "Well, I doubt it but I'll write him a letter."
