I'm currently doing a FPS, and when I came to the weapons I had some thoughts about gameplay elements related to these;
So I'm interested in hearing your opinion:

In most current shooter games, the crosshair is kind of scaling while moving so it looses accuracy. Do you think that this is necessary for a good shooter?
And the second thing, in nearly all FPS you can press the right mouse key and the weapon gets to the middle of the screen so the player can aim over it instead of the crosshair. What do you think about that?
I'm asking all these questions because I'd like to do a more old-school thing... well, not THAT old-school, more like these games that are called "old-school" because they don't have a cover system or weapon tuning (like Unreal2 or Quake4 or Legendary or...).
However, I do not think that these things are typical for an old-school shooter, but I just want to have more opinions about that.
