People who love games should make them, but people who want to make a living from games need to understand that is a business that doesn't always reward passion. The good news for this guy is he has dipped his toe in the water and learned from it. Experience always makes you better. Others have pointed out the poor return on creating your own game engine. Here is a point I would make: If it is a business for you, think about what kind of game people are likely to buy, as opposed to what kind of game you can do well.

Also, people who enjoy making games often are fans of similar games. There are ways to test how much traction your game is likely to find in the market before you make it.
