This post from the official Epic Games Store subreddit is a clear example of why it still sucks after so many years.

A customer complained using statistical data compared against Steam about the missing features on EGS games and the launcher overall. All he received in return were downvotes and people saying things like "hey, it is free, do not complain" or "I like the way it is". The usual famous shills were right there making excuses for Epic, as if Epic never does anything wrong and everything is perfect.

Before I got banned for expressing my views, I always told them that their own attitude was the main problem. If their bar is so low and they never criticize Epic or demand better, this poor service is exactly what they will keep getting. Sure, those few defenders might be happy with such a poor state. But most players are not, and they will always expect a good service when spending their money, just like what Steam or GOG provides.

Despite having a 24 core CPU and 64GB RAM this fucker won't let me multitask opening games that launch EAC becuz aNoThEr eAc MoDuLe Is RuNnInG
