Everybody in the gaming industry has a great idea for a game. The desire to see that idea become a reality is what brought many to this industry. Sadly, the quality of this idea – or even of the game itself – isn't enough to guarantee a commercial success: critically acclaimed games like Psychonauts and Beyond Good and Evil have sold far fewer sales than they deserved.
How can you tell if a game has the potential to become a huge hit based only on its design? Marketing executives at major publishers have sophisticated tools to evaluate that kind of things, but you don't need all that complexity to find the potential of your idea. With just a few questions, you can evaluate the marketability of your game. Gamasutra compiled these questions in a simple test that you can use in 10 minutes.
