Is it possible to have more than one save file per game?or will it just re-write the previous save data?
You can have more than one save file, 3 in fact and it doesn’t rewrite previous data.
You can have up to three save files ingame at one time. In the main menu, where you can select Continue and New Game, it’ll give you an option to select
Save Files and you can select either Slot 1, 2, or 3.
You can technically have more than 3 as well, but this requires renaming your save files or storing them in an external place other than your Saved Games folder.
