Well its a good thing that no real money is involved because otherwise you would be that much poorer.
Trying playing it on the hardest difficulty and then come back and tell me you don't mind when an enemy pops out of nowhere to rub you out when you are literally 2 seconds from a save point.
And why play on harder difficulties you ask? Because I cannot stand the use of infinite health (one of the worst contributions ever made by Halo to the fps genre).
I have played every iteration of COD, I was under no misapprehension that COD4 was first and foremost an arcade shooter. I was not after a military simulation, but that being said that does not mean I should just accept shitty game play mechanics and features which just scream consolitus (fixed save points, infinite health)
All fair points. I guess the game wasn't for you, then.
