There are a million ways to criticize me while accepting the basic premise that some games get overlooked and their sales are affected by being on steam.
For all the talk of oversaturation no one seems to have a solution other than curation though, which is ironically an even worse situation for the developers currently struggling most because they're the least likely to be chosen on a curated platform in the first place.
If steam was less saturated you wouldn't suddenly see more developers getting the attention they deserve, you'd see less. The only difference would be that the opportunity to succeed for many wouldn't exist in the first place. And that's without going into how games are chosen and which are deserving to be chosen and who it'd tend to favour.
One glance at EGS says it all. Curated storefronts don't help the smallest or most niche developers at all, they help developers and games that would already be likely to succeed on an uncurated platform. Red Dead, Borderlands, Shenmue, Outer Worlds and Hades would never, ever struggle on steam. The people who get favours are the safe picks more often than not.
On the other hand there're countless games on steam that have succeeded where they'd otherwise go ignored, sometimes to the extent where other platform holders take notice and extend them further opportunities as result. I don't see that happening in a major way on a single curated platform and I don't see that changing any time soon.
Funny enough even some devs who complain the loudest about the volume of games on steam are best known as a result of the success they've had there. They had no issue when their game was on the top of the heap and would seem to have no issue being one of the few chosen to be highlighted again on a curated platform either. The problem is that not everyone can succeed but the opportunity to do so equally is always a better circumstance for those who need it most than being gated from participating entirely.
