I have this idea for a game that has been in my head for around 2 years now. I really want to make this game but I don't know how I should execute it. I've made games before, but this one is special to me. I want it to be the best game I make. There are two main reasons that I have not made this game yet. First is because I have not settled on a good story for it. The second is because I don't know what game engine I want to make it in. I have the options of clickteam fusion 2.5, or unreal engine 5. I don't know weather or not it should be a 2d or 3d game.
