Feedback on my new videogame idea?

I'm only 16, but using Greek mythology, I was thinking it'd be called "Reign of Zeus" and itd use the Unreal game Engine. it'd be third person and the synopsis is you start of as Zeus as a kid right after his bretheren have been eatin by Kronos. and you get accustomed with the game play as a child Zeus and get mor powers as you progress throught his adolescene and move on to early adult hood where you move on to make your way to Kronos,he'd be like halfway thorughout the game and after you bet him the gameplay could be to start the construction of Mt. Olympus and expand it into an empire and you could customize it any which way you wanted too and go on mission in Ancient Greek to conquer like the remaining Titans. online gmeplay could be that you would choose one of the gods such as Ares or Poseidon and battle on a large scale Ancient Greece battlefield to the death or something along those lines..
