Someone said that when a service is free, you are the product.
Basically it falls down into two categories:
1. Free games that serve to promote a platform (like steam for example)
2. Free games that are designed to hook you in so that you spend more on microtransactions later.
Valve’s most popular titles are indeed free to play without any need to spend a dime, but they promote Steam which is Valve’s biggest source of income.
Other games (particularly mobile ones) do have microtransactions that are cleverly implemented to sucker you in so that you spend more and more money. There is a term called ‘whale’ that defines people who spend vast amounts of money in these games.
