>>1424028NFS: Shift. It's not available on later platforms, and it's one of the best GT-style racing games, especially when it comes to the actual races, which mix it up from Forza's tedious "start at the back and overtake a dozen cars"*100 campaign.
Rock Band 3, particularly with the xbox-only peripherals like the bass and the stage kit
Destiny has a low population but is surprisingly not dead. It remains frozen in time at a point that is now recognised as one of the best in the history of the franchise. Matchmaking for the most part still works, even though it's nearly ten years old.
Beautiful Katamari is the best Katamari, though it plays best on XSX. Same for SSX3.
Morrowind is the best Elder Scrolls, though it plays best on PC.
THUG is the best Tony Hawk game, and the best introduction to the series. THUG2 is also great, and may even have better gameplay, but it marks the point where the publisher just started crunching them out year after year after year. AW is a lot of people's favourite, and it represents the final form of the TH4 engine, but THUG is the best overall package. After that, Activision reassigned Neversoft to Guitar Hero, ruining both franchises. If you've never tried Tony Hawk games, give THUG a go.
>>1424030Xbox Minecraft is its own development branch, and a lot of people prefer it to the direction that Minecraft has gone. It's the only one with decent controller support, current minecraft-on-xbox is a trainwreck.
