Confirm Menu Choices

The sciences of Human-Computer Interaction and Interface Design are very well represented in electronic games. Menus, buttons, toggles, and making selections is inherent to the process of interacting with almost every game ever made.
Because most games provide an interface unique unto that title, standardized conventions of design can be few and far between.  Because most platforms have different methods of input, no one action can be trusted to behave the same way from one game to the next.
 
Whether you find it bacon-saving or redundantly annoying, some games choose to confirm your actions immediately after you make them, as though you might have made the choice mistakenly.  This design element can serve as a guard against hasty decisions, but most often doubles the amount of time and interactions required for the player to make decisions.  It can triple the actions required if the confirmation defaults to No.
 
Example: navigating and selecting a menu option that says Load Data, and then having to choose a Yes or No prompt asking if you would like to load your data.
