Have you ever had ideas that could not implemented? Post them here, three at a time! Perhaps someone could use it for themselves?
Idea 1: A game where you play as a person. Soon you understand that you are actually the past self of someone else. Later, you find yourself in the room you started in. You see a person like you, picking up stuff and moving. Then, in a place where your past self couldn’t’t go, you see a note written by your future self.
Idea 2: You are one of the warriors of Greece, about to fight a war. The enemies come on a ship and when you look, you see Romans. Epic Greece v Roman battle!
Idea 3: You are now an old (wo)man. When searching the attic, you find a scientific paper proving that aliens exist. And another thing is that you wrote the paper.
