I think everyone should jz go play paintball. Speedball version.
After that play Promod COD4.
After that play Pam4 or Stock COD4.
Then u ll realised playing paintball
... ur gun sways... especially WHEN YOU RUN!
... aiming down sights... your neck GETS TIRED!
... and if the team manages to sneak in a 'snake'. No matter how skillful the opponent is in shooting, if he 's not perceptive. The 'snake' can take the whole team down...

OMG... i m rambling hahahaha
point is COD4 is realistc... speedball is like playing pam4 in shipment
