However, users frequently face challenges regarding key legitimacy, "Used CD Key" errors on Steam, and the abundance of non-functional keys circulating on the internet.
Creating, distributing, or using (key generators), cracked CD keys from online databases, or warez copies of Empire Earth III violates copyright law.
