Call of Duty 3
It gets intense in some places. Easy mode is basicly, "Gimmi a gun and let me shoot at targates" but still very fun. The veriety of guns is amazing. Some of my favorites are the MP44, Thompson, M1 Grand, Springfield, and the MG42. Aswell as shooting at Germans, you can get attacked and end up in a wrestling fight with them. Your squad is very helpful most of the time. And you fight with many different alies including America, Poland, the French, and more.
