Why many shooters will not be more popular then COD (one of many reasons.)

[Retardinator]

What I really want to know though, is how would you make your FPS unique over another? Put it in a different setting? That's not unique. Add squads? You still haven't changed the core of the game. Where can the FPS genre go on from here?

The core is first person shooting and, as we can see, all devs stick to that. Although you do make an interesting point; I'm sure someone can come up with a nice game-changer. Either that or we'll see a decline in FPS games in general. I'd say it's about time.
