Your probably right, FM is becoming more complex and harder to master, because thats what most want. Its boring just buying the best players, picking an 11 and hitting continue for the next 3 weeks. You can learn plenty in FM, but to do it, you need to really work at it. The answers wont just land on your lap. Your kinda comparing apples and oranges as well. COD is not a replication of war at all, its a shooting game designed to mimic a war like scenario, FM actually attempts to follow real life football where possible, they are completely different.
