It depends on how much memory the games take.
It has 10 gigs
yes
maybe the saved game is messed up i always backup my saved games on my computer. if your saved game doesn't work there is a small chance you can fix it
Zero, only the Arcade unit has internal storage built in. Otherwise you need an HDD to save games.
Go to your saved games and Press delete.
2-4 games can be saved, I've done some research and this is what most people say
Xbox 360 games that u already own on the 360 can be sent to your Xbox one with your saved data.
the xbox harddrive is where all your stuff is stored [profiles and saved games]. if you own a xbox 360 you should know that.. . . .
probably there are many xbox games out there
Yes but it does not transfer your saved data (how far you got on campaign or your level)
You can play many regular Xbox games on the Xbox 360.
It doesnt have gigs, it has a 256 mega bite memory core although you can buy a hardrive for it.
