Ok , I wont argue it does depend on the type of the game. And , burst mode can prevent the player from shooting 100's of bullets when he gets surprised , I was just shareing my opinion on this
As for realistic games , I suggest you play I.G.I. (the first part) it might give some ideas I dont remember the rate of fire in the game,but I do remember that a few bullets can kill you very quickly and that was the part that I loved in this game...(too bad it has some problems with my video card,I dont have a crosshair,mouse,GUI...even the main menu )

PS.: I realy like the gravity cheat when I fell in that hole I though I have to restart the application,and I'm too lazy for that,and I accidentaly found the cheat
