6. A 'Time Since Last Save' Notification
Praise be to Naughty Dog, who've had this practice down since the first Uncharted - and what a helpful one it is. Every title should always tell you when you last saved, and not necessarily in a time of day/timestamp kind of way either. What's best is a '5 minutes since last save', or just a timer counting up from your last checkpoint, it's the fastest way to get a handle on your playtime over trying to remember what you did on a given date. Naughty Dog would continue this feature through the other two Uncharted games and also The Last of Us, making it something that's already in practice, but rarely seen in other titles.
