The role that talent plays in every success story is usually grossly overestimated. When people display a high level of skill in some area, it’s generally assumed that they were born under a lucky star. This couldn't be further from the truth. Success is just the tip of the iceberg. Achieving a goal is merely a short moment of reaping the rewards of incredible sacrifices and thousands of hours of hard work behind the scenes.
If you commit yourself to a project that has low market potential, you’re setting yourself up for failure, at least in a business sense. If you try to replicate the success of a popular game, chances are you’ll create a soulless clone that nobody, including you, will be excited about. While I’m not going to tell you what game you should make, I will help you consider the factors that will likely influence the outcome of your decision.
