If i restart my ps3 will games that i have bought from the ps store also be deleted?

If you restart it
It will go to Its default settings
But if I Restore it
Sorry bro
Your all good stuff will be gone
So do that at your own risk

Yes. If you factory reset your PS3 then *everything* will be gone, your system will essentially go back to its 'just out of the box' state.

All patches, saves, and game files not backed-up onto removable storage or stored in the save cloud will be *deleted forever*.

Once you have finished, however, log back in the PSN under the *same* email you bought Minecraft under and you can re-download Minecraft by either going to its store page or your previous purchases page.

Note: you will have to patch all the way back up to get into the PSN, make sure to take that time into account.

Just save it on a usb. But yes it would delete it all.
