Game engines are no longer 'games' engines, in my opinion. Its really far better to pitch them as "Interface" engines, in as much as a significant majority of the interaction with the engine is to get an interface on the screen - whether that be for gaming purposes, or application interaction.

These days, the line is very blurred, don't you think?
