We contacted Microsoft, where a spokesman told us the new game "
pushes the limits" of older Xboxes, and says it
"requires 8 gigs of free space," which many older units no longer have. They were shipped with 20GB, but much of that space is now taken up with data from other games.
Dave Allen, though, says like a lot of gamers, he may soon have to upgrade to a newer Xbox, either the newest 360 or the upcoming Xbox One. With the new model coming out, a lot of people may soon be saying goodbye to their older models.
A footnote: Some Xbox owners say they have found workarounds posted online that don't require purchasing an external drive, that include unplugging the console and clearing the Xbox's data cache.
So if you're having issues, check the possible fixes before you pitch your older Xbox, so you don't waste your money.
