Call of Duty Experience

I have been playing COD since I was in about 4th Grade, my first ever COD was World at War and I never looked back... until recently because the new Call of Duty's are a disgrace. My ranks are...

1. COD 4: 8th Prestige
2. COD WaW: 10th Prestige
3. COD MW2: 10th Prestige
4. COD Black Ops: 14th Prestige
5. COD MW3: 13th Prestige
6. COD Black Ops 2: 8th Prestige

It drops off after that...
