Here's that good faith you asked for:
> you're not charging arbitrary, excessive platform access fees
What's your legally enforceable definition of arbitrary? What's your legally enforceable definition of excessive? How do they apply to Apple and not to (for example) the Steam store?
> Sony for example seems to have a pretty positive relationship
Emphasis on "seems". These relationships involve very aggressive NDAs which would have a chilling effect on developers speaking out. Not to mention most developers will work for very large companies who would frown upon freelancing their opinions about a corporate relationship that is responsible for 50% or 100% of the developer's revenues.
Compare that to the App Store, where a million rando developers have paid their $99 and are complaining because Apple won't publish their malware or torch app.
> There's also various accounts of Sony providing support for its developers
There are (relatively speaking) an extremely tiny number of game developers on these platforms, and a lot of potential upside in landing exclusives, so you can expect such largesse and personal treatment from Sony and Microsoft.
> including launching a $10 million fund
For the video games industry, $10 million is crumbs. No, it's fractions of crumbs. No, it's atoms. I haven't looked into this PR exercise aka "fund" beyond the link you offered, but how much do you want to bet that access to that fund requires a period of console exclusivity in return?
> I'd imagine we'd hear a lot more negative stories
Again, the number of console publishing licenses is relatively tiny.
> But it also works out in game developers' favor.
Does it? Or does it just lock out new entrants in the hardware space? If Sony and Microsoft were unable to sell consoles at a loss, perhaps new market entrants would be able to create new console platforms of similar quality, and compete for developers by offering better financial terms.
