Should i get cod 4 game of the year edition or original? or should i just buy resistance 2?

May be...

Game of the Year edition includes the 4 extra maps so get that. In total that is 20 maps. If you are an online player that is a must buy. If you don't play online get Resistance 2

Call of Duty sucks. It's so over rated. Resistance 2 blows it out of the water, and the online is superb. Everyone plays COD, which is really all it has going for it. It's time to let go of old games and accept the new.. Resistance 2, aside from Dead Space, is the best game I have ever played.

Resistance 2

get world at war

if u get 4 get game of the year

Get both, they are both great games
