I'm building a mobile game for a client in Unity. To save time, we started with a template game from the Asset Store that had some of the features that the client wants.
The game includes a progression system and shop, so we save the user's scores, progress, in-game currency, inventory, etc. We currently have no plans to export the save data.
The template game uses PlayerPrefs to store all save data. Is this bad practice? Assuming we don't include a button that calls
PlayerPrefs.DeleteAll(), is there any extra risk associated with using PlayerPrefs instead of external files to store the player's data?
