It’s not a hard thing to get. Over the years Valve has had relatively low amount of blunders and for the most part they were of the misjudging customer base kind but ultimately they have been very consumer oriented and have provided great value for the money. From universal refund policy to family sharing and similar. Their service consists of many benefits for the consumer but all of that is charged from the developer. Very hard not to like such approach.

Epic on the other hand did the opposite. They catered to developers and inconvenienced consumers. You get to pay the same price as everywhere but you are forced to get exclusives from them and you don’t get any of the benefits Steam has. Am in fact surprised it gained as much popularity as it did. Goes to show people will sell their own pride for occasional free game you don’t even get to chose.
