There are many different reasons why someone might make a game and release it for free. Often, it’s because the person is just having fun and wants to share their creation with others, or share a story they’ve written. With game businesses, releasing a game for free sometimes revolves around adding microtransactions to the game, to get people playing the game and then to get them to pay some money to enhance their game experience.
There is another reason businesses should consider releasing a game for free, and not a game saddled with microtransactions, but truly free. It’s the same reason so many e-books are offered for free.
In the e-book publishing world authors often offer some of their books for free to help their books gain attention in the hopes that people will read their books and like them, and then seek out their other books and buy them. When it comes to book series, it’s the same idea. The first book of the series might be offered for free so that people are more likely to read it and if they like it, buy the rest of the books in the series.
The same can be done with games. A developer or publisher could offer a few games for free so that people play them and if they like them, look for other games from that developer or publisher. Or they can release the first game in a series for free to gain more attention for the rest of the series.
There is real value is offering games for free, both for independent developers and large publishing houses. When it comes to releasing games, free games have a value that should be considered.
