Red Dead, as modern warfare gets boring after a while
The answer here is completely dependent on your game style, but I would say Red Dead Redemption.
Most people would agree that red dead redemption is the better game on most accounts
Both games are highly rated, popular top sellers that are also rated mature
Gears of war 3 would be a good game to buy if not buy Call of Duty Modern Warfare 3. Red Dead Redemption would also be a great choice.
red dead
Modern Warfare 3
There is no such thing as Red Dead Redemption black there is only the regular Red Dead Redemption and Red Dead Redemption limited edition.
It's a perk
No. Red Dead redemption has much more violence and other content that could potentially be harmful to your son. The worst content in call of duty may be occasional harsh language and blood splatters here and there. There is a level with an airport massacre, but you have the option to skip it.
You need to go to Game Marketplace. Find Red Dead Redemption. Then there should be a DLC list.
Call of Duty Modern Warfare 2, Left 4 Dead 2, Halo ODST
There are two, Red Dead Revolver, and Red Dead Redemption and Red Dead Redemption Undead Nightmare
