I wouldn't mind seeing some Jagers in a video game. They have pretty awesome hats.
As for COD, it's okay. Some companies make the same game every year and it still sells. Well, I guess they change a few things around... like names and titles.
Actually, I've never played those games, so maybe they change a lot.
The list of Call of Duty from best to worst (in my opinion): Modern Warfare, CoD2, CoD, WaW & BO (only because of zombies), MW2, and finally CoD3. Yeah, the only reason MW2 was bad compared to Modern Warfare was because of the lack of Dedicated Servers. At that point though, MW2 was only being tailored for the consoles and not the PC. I just wish Treyarch would make a standalone zombies game with 10 maps, with DLC content of two maps or more. One "Tank, Richtofen, Nikolai, and Takeo" map, and one with 4 different characters. Quite honestly, I want to see a zombies map with Abe Lincoln, George Washington, Winston Churchill, and Bill Clinton. THAT would be funny (in respects to what they would say).
Anyways, when the Xbox 3 releases, they will more than likely have a CoD game as the flagship release title.
