Clones: Five Nights at Freddy's and Minecraft have been DONE TO DEATH. Try making a game with similar mechanics without being a blatant carbon copy. Or you know, you could like make a whole new game.

Don't look too far ahead of what you want to create. Don't make a game that requires a whole 2 and up minute tutorial, just make something simple, that will grab people's attention without being complicated.

Start out with a simple game mechanic, make a game egine and then start making the graphics and the sounds nice.
