no i dont think it does, it brings more fun and meaning to the game instead of staying the same prestige like haveing all the good guns and not gaining any points
its cool because it gives you a feeling of pride and knowing that you went through it all and you did 11 levels of 55's because you have to do the first 55
It is pretty gud, but when u stay 0 prestige 55, you will be more likely to compete against other UNDER 55's 0 prestige, so kinda unfair in my opinion bust still, it is pretty cool, im on 5th at lvl 30 or so, (last probably, I got pretty sick of losin dem guns.).
Im on prestige 8 atm and im still going up. i cant imagine playing cod4 without doing prestige cause it'll just get boring and ur not achieving anything apart from general leaderboards.
