Well, Playnite exists. It's free, open source, extensible, and the dev caters well to feedback. The big 5.0 update is out soon and currently in open beta. More on reddit.com

In addition to what others posted, I want to add this. https://www.reddit.com/r/fuckepic/comments/bs4kh6/rfuckepic_for_dummies_a_quick_breakdown/ To put it bluntly, the CEO is a notorious liar that talks out of his ass. Epic continuously uses anti-consumer and monopolistic business practices to shoehorn their way into a market to the detriment of consumer freedom and health. They employed/employ information control and spin the so called "epic narrative" twisting reality to a make-belief world where tim sweeny is the savior of video gaming, ignoring the fact that he himself abandoned the pc market long ago. I'll also add this informative Video going into more detail about the whole 12/88 (this one is bad in short) and the 30/70 split (which according to tim swiney is evil, which is all based on lies and bs). There is also a lot more, like how the unreal ip was handled, or changes to the engine etc etc etc. There is just such an immensely long list of shit they have done and are doing that are all reasons to not want to touch them even with a 10 foot pole as a consumer. Even if you only use the launcher for free games, you are still feeding into their metrics supporting all this industry-ruining crap. More on reddit.com
