Need ideas? Play with the name of a game you know and try to imagine what the forgotten prequel would be called! Some examples of this:
| Known game | Unknown prequel |
| Dark Souls | Dark Soul |
| Tetris | TriTris |
| Horizon Zero Dawn | Horizon Negative One Dawn |
| Temple Run | Temple Walk |
| Karate Champ | Karate Chump |
| Gauntlet | Mitten |
| Final Fantasy | First Fantasy |
| Centipede | Decipede |
| Strider | Stumbler |
| Forbidden Forest | Welcome Woods |
| Quake | Quack |
Then think about what a game with that title would be like. Is Karate Chump about what happens when he is always getting beaten up? Is Welcome Woods a peaceful walking simulator? Is the hero in Quack of the Mallard variety?
