In order for it to be a FPS it has to be a shooter. Now call it whatever you will, but it isnt a shooter. You do shoot in it. But you also shoot in ED, and is not a shooter. Call it what you will, just not a shooter. Or something like a puzzle...you know...
FPA is its description, not a new genre that was created. FPS is classified under shooter. Consider FPA under adventure.
