If I'm honest, I don't disagree.
I would love for Steam to have **actual competition. Which is difficult, sure, but you could run a slightly less feature-rich store, take less of a cut, and pass the reduction fully on to consumers and you'd be an easy choice for many gamers.
But that's not what Epic is after. They tried to go hard after the sellers, figuring that if they can corner enough fo the market with exclusives the buyers will have to come. But they underestimated that even their nigh-infinite coffers struggle to keep up with the raw amount of games releasing, and also the unpredictability of the indie market where you can't really know what to buy as an exclusive.
Nevermind that buying one is a good way to make it forgotten.
So yeah, fully agreed. Compared to Epic, I vastly prefer Steam's 30% cut. As the consumer I pay the same anyways, and Steam offers lots of stuff for it like forums, a client that boots before the heat death of the universe, in-house streaming, library sharing, cloud sync that sometimes works.
Same, I always check whether GOG has a game first, and whether it’s patched up to par. Sadly, surprisingly often while games release on GOG they then lack features (although personally I do not really care about achievements) or worse, the devs give up on releasing patches for the non-Steam versions.
This is almost always a situation that can be pinned on Steam, actually. The games that end up doing this are usually using Steamworks, which essentially forces them into a sort of soft-exclusivity on Steam since their multiplayer features and such can only exist there.
But Steam doesn't force them to use Steamworks, so I don't really see "steam's fault" fault here. Although, of course, it'd be cool if Steamworks would work for non-steam games at least for modding/multiplayer. Granted.
That's the point. No, nobody's forcing them to use Steamworks (especially since Epic has rolled out their cross-platform, store-and-OS-agnostic free competitor to it), but anyone who chooses to do so (which is a lot of devs) ends up locking those features to Steam (barring a ton of extra work for themselves) simply because of Valve's chosen policy.
Don't think Valve doesn't understand this. They found a way to get devs to all but lock their games to Steam and thank Valve for the opportunity to do it.
