Steam has so many more features than any other platform.
First to market or not, that's why steam is number one.
None of its competitors offer the community, market, discussion boards, rating system, friend system functionality and overall reliability that steam does.
It has competition, just not on PC.
Epic is atrociously bad. From hampering system performance to a total lack of any of the above features, using epic sucks.
The Xbox app is somehow seemongly always broken despite literally being developed by the platform holders and with a shit load of cash behind it.
I don't love the idea of a steam monopoly but you gotta also give them their flowers, it's a fantastic storefront, arguably the best when considering all gaming platforms that exist even outside of PC.
Talk about putting part of your life's work completely out to pasture.
I give it a year. What a shame.
