Steam vs GoG is a turf war, Epic vs anything will make people side with anything. The problem is that Epic has a shitty store with shitty features, and the only way it can compete with the others out there is to pay piles of money to game devs so they make their game exclusive to their store for some time. So usually people just ignore the game until it comes up in another store, and most of us have completely forgotten about it by then so when we find out just add it to the wishlist and wait for a 90% discount in a while. The game has been out for years at that point so a massive discount is expected soon and you already waited years to play, you can wait a bit more and save money, plus that teaches companies that signing exclusivity contracts is a shit deal.
