I'm a bit confused by this post. Not by what you posted but by the 3 likes you got. FPS as an acronym for game genre means First Person Shooter. So him saying a FPS that's not an FPS implies you have gun but you really don't use it. It's just for show mostly. When you say FPS what does the S mean to you?
Scorn has been in the public eye for uh .. years. And at first it was touted as a horror shooter; kind like, let's say, Clive Barker Undying.
Now, shooters tend to have some similarities in the gameplay. If you look at diverse shooters, from Metro to Half Life, from Bioshock to FEAR, or Quake and Halo, they all have very strong gameplay elements in common. Scorn doesn't.
Now this isn't necessarily a bad thing, for example we could mention Portal, which is both played in first person, AND you have a gun. And you have movement mechanics similar to many high end competitive shooters, BUT you dont actually shoot. Or, at most, you shoot the geometry of the arena itself, and not moving targets.
But, despite Portal being very good, it's not "a shooter". The gameplay is completely different from Doom or Prey or STALKER.
Now, i'm a big FPS guy so, you give me a FPS and i'm happy with pretty much anything, be it Hard Reset, Singularity, Timesplitters, or what not. I like that particular gameplay they all have in common, despite how different between them they might be.
However, if you give me games like Superhot, or Mirror's Edge, despite them being technically FPS, i wouldn't like them.
It's the "tomato is a fruit" argument.
Now, from what i see, Scorn has more in common with, idk, Monkey Island, if Monkey Island had no humour. You slowly walk around and try to identify what you're looking at, find a puzzle, solve the puzzle, and move forward to another puzzle. Not completely a walking simulator, but more in common with Myst or Riven than with Unreal Tournament.
And instead, the older videos promoting Scorn were very much trying to give an impression of this being a FPS. You wake up, and you are horrified at where you are.
The you find a thing, look at it, and go "IT'S A GUN !!". Cue images of mobs being shot. The another image of you taking the first gun off, and attaching A NEW GUN !! And BAM!, more mobs taking shotgun shells to the face.
But it's not that.
