Hey,
I think a nice feature for the game would be the ability to autosave it. With the older games in this franchise that wasn't available and when the game chrashed, you lost your unsaved progress. But please: If you add this feature, make it opt-in or opt-out and not only auto-save, cause some people might prefer saving it manually.
I'm looking forward to this game! (so please don't screw it up!)
