Both are solid ports, but Modern Warfare 2 (2009) is generally the superior experience on Wii.
| Aspect | Modern Warfare 2 | World at War |
|---|---|---|
| Setting | Modern, cinematic | WWII (Pacific/Europe), gritty |

Note: Wii online services (Nintendo Wi-Fi Connection) shut down in 2014. Online play requires private servers (Wiimmfi).
