Call of Duty : German don't know play ! WHY ?

You think you're good but you suck without :

Cod 4 : P90
Cod 5 : PPSH
MW2 : UMP / ACR
BO1 : AK74u
MW3 : ACR or Mp7
BO2 : Scar or AN94

Poor German People, they buy game for play with 1 or 2 weapons.
Maybe (probably, surely) you must buy Sim city or Sims.
FPS is not for you, noobs.
