pardon me but i don't get you. u mean if i root my files will not be gone ? and my save games remain ?
to root, needs to unlock bootloader and all user data are wiped off..
once done, you can push/flash the root files.. after that can reroot anytime if you haven't relock the bootloader... to backup data can use Titanium Backup
There's another app Helium seems to backup userdata without root.. haven't tried yet though..
