I think their market dominance makes it an uphill battle for a dev to not put their games on steam. I don’t think that’s much of a problem right now because Valve has been reliable, but all it takes is a bad turn of events at Valve leadership for that to change. I think they are a gatekeeper only insofar as they have market dominance and a platform with games with DRM
Some titles have been very popular without steam, Dark and Darker is a good example of this, GTA 5 another.
I’m not going to pretend they don’t have the most sales, but they also have objectively the best platform. People love it.
As a gamer, there isn’t too much I can do about it, except buy games from other stores where the developers offer their games. As a developer, if I’m worried about Valve becoming abusive, it makes sense for me to use more than one marketplace, or a different marketplace than Valve altogether. Since Valve doesn’t seem to have a lot of exclusivity deals, this either means it costs more for developers to maintain multiple distribution channels, or they don’t think it benefits them to have multiple distribution channels. That said, the continued existence of those other distribution channels leaves the option to leave if they don’t like Valve’s behavior.
As a gamer, all I can do is support other stores, and I do.
