Call of Duty II
The sequel to the original improved on every aspect of that first game. It looked better. It felt better. It had more multiplayer options and a more impressive campaign. And for those who bought an Xbox 360 it was a real easy way to show off the power of your new console. (I did this.) CoD2 also moved the franchise to auto-healing, which ended up being a big change that probably helped it click with more people and was another reason the series became huge. It’s almost the best Call of Duty game set during World War II. Almost.
