Notes:
Both are for PC
Battlefield 1942: The Complete Collection is multiplayer only
Battlefield 1942: The Complete Collection contains Battlefield 1942, Battlefield 1942: Vietnam, Battlefield 1942: Road to Rome, and Battlefield 1942: Secret Weapons of WWII
Call of Duty 4: Modern Warfare has single and multiplayer (duh)
Call of Duty 4: Modern Warfare contains Variety Map Pack thanks to NVidia being awesome and sponsoring it
Dunno if both are used or new
Battlefield: 1942 is about 10 USD
Call of Duty 4: Modern Warfare is about 30 USD
Both are from GameStop

So which one should I buy, or should I save it for NX? (Waiting for free Black Ops)
/Discuss, reason, and give me advice on what to buy


Please and thanks,
