COD 4 is the greatest game ever. Rainbow Six is a little to close to the last Vegas while COD turned the franchise upside down. Plus, party-based matchmaking in COD FTW.
COD 4 is much more advancing in quality and graphics, but i have to go with R6V2. You can customize your character and it has multiple amounts of exotic guns.
well depends on what you like if you like a magnificent campaign rainbow six vegas 2 if your looking for a a magnificent online cod4 (only problem really is noobtubes -_-) i didnt really like cod4s campaign much since you had to do everything but the actual story of it was good jsut not the gameplay. also cod4 is more of a run'n'gun type of game and rainbow six vegas 2 is a tactical shooter so thats another factor
Rainbow 6 Vegas 2 is the BEST game ever!! They only problem i can find is the fact of how much blood comes out. When you CAREFULLY shoot an ally, like the girl who unlocks the gate for you, in the hand, the wall on the other side is COVERED in blood. Too much and its not correct. Good game other wise! Rainbow 6 Vegas 2 ROCKS!!!!!!
