NO, buy Quantum of Solace Wii instead, it have DEFINITELY have great splitscreen co-op even the graphics are sacrificed for it. I will definitely buy Quantum of Solace Wii instead than COD WAW Wii maybe next month because of the splitscreen mode.
And the maps are suitable for 2-4 players, you wont end up finding your enemies QoS definite buy.
end of core gaming days prediction:
E3 2006-The beginning of the end. Wii introduced
E3 2008- Armageddon. Wii motion plus introduced. Wii Music. Reggie says Animal crossing was a core game. Massive disappointment. many Wii core gamers selling their Wii.
E3 2010- Tape runs out
