It is supposed to be an FPS, with a really good story.  I believe that Zero Punctuation had it in the top 5, if not game of the year.  For me, it is an FPS, and I really didn't feel like dropping money on another FPS, even if it has a great story.  I look for games, not works of fiction, when I get a game.  My focus is on gameplay mainly.

Another part to this of my asking, is with games on the Playstation platform, Sony's marketing is continually blamed for them not meeting expectations.

I bought a steam key from GMG for €3,50 a little while ago. Yet to play tho

Some of the gaming media sold me on the game. It was pretty different than it was advertised. It was solid game that makes you uncomfortable (in a good way) while playing it. Would not have been worth full price but for $6 i paid it was quite good.

the kind of marketing Sony does... free with PS+

I think the marketing of this game is a really tough thing to do. If you advertise it as what it is you spoil too much, and the WTF experience would get lost. But advertising it as a generic shooter didn´t work too good because a lost of gamers are sick of generic shooters so they didn´t an ugly Third Person military Shooter. Which is a shame this games turned to be one of the biggest surprises of 2012.

People who already know the game exists isn't what marketing is for.  The marketing is for people who don't know the game exists.

bad marketing only applies to Sony exclusives. if Spec Ops is a good game, and not a COD clone then i'm all in.

Marketing doesn't really sell me games.

I guess they should tell me as much about the game and its features (multiplayer, physics, level editor, etc) as possible, as I need to know that if I am to even consider buying a game.

FPS means First Person Shooter which includes a first person view. Spec Ops The Line is Third Person Shooter. You can get it for 20€ and it is a really good it is something like Apocalypse Now.
