According to me this is the best rts game ever in its category. You start from stonage and do the same things as you did in age of empires. But when you reach more advanced ages like copper age and IT age you couldsend missiles on enmy territory use f18 fighter planes , use stealth bombers, artillery , etc. You have to get oil ,minerals and all the research. You can sign treaties and yes you can use nuke power also.
