Best CoD game: MW2 and World at War are tied for best CoD game on my list. Both had great stories, great missions, great characters... both brilliant.
Worst CoD game: Big Red One, no question. The only good missions were Liberators and The Great Crusade, and Vic, Kelly and Hawk were the only good characters. All the other missions were boring, being either too easy or too hard, all the other characters were downright tedious, and to top it off, the graphics, particularly character and reload animations, were dreadful, even by PS2 standards.
How about you? Which game was da bomb, and which game deserved to be bombed?
