Higher revenue cut for publishers. That’s it. This is just a big anti-consumer pissing contest about who gets a bigger slice of the pie when a sale is made. Everything else is just distracting noise. If Valve charged 5% then none of this other stuff would matter. Valve charges 30% base with some sweetheart deals for devs who sell millions of copies. Same as Sony, Nintendo, Apple, and most other online software marketplaces.
This is a high percentage to pay vs retail margins for a brick & mortar storefront, but a reasonable percentage when you think of it as a customer acquisition cost. So the question is, did I go to Steam to buy the game or did I go to Steam and buy the game? Everyone will have a different opinion on this, but in my opinion Valve revived PC gaming when it was on the brink, and a large percentage of sales that happen on the platform are because of the eyeballs it brings and the value it delivers.
Borderlands 4 coming back to Steam is strong evidence of this, even with Epic essentially paying developers the difference in potential lost sales out of pocket. You can’t pay for the lost conversations, word-of-mouth, and other “free” advertising that those lost sales would have generated. So Borderlands 3 looks great on a balance sheet, but nobody really liked it or cared about it, and Epic won’t pay you to make games nobody plays forever.
It might seem better for the storefront to take less of a cut from a consumer perspective, but in reality it barely matters. This doesn’t go towards reducing game costs for consumers or improving bonuses & wages for developers. The market has already been set. Any behind the scenes change in revenue sharing just goes to the next group in line, which is of course the already wealthy and massive publishers.
So do whatever works for you. Just don’t let them pull the wool over your eyes and act like this fight is about anything other than which already very rich people get slightly richer.
