I think the biggest issue is titles; what people expect of mobile games, perpetuating itself into a weak catalog of original titles, with a few good ports. Mobile games are largely designed to be heavily-monitized, Games as a Service, and/or gacha titles… profitable design choices, but not because they make games better.
Having a more standard control scheme would help get more ports of console games, but I’d love to see more mobile games that use the existing interface/formfactor well. Pokemon Go circa 2018 was a good game that only works on mobile, and I’d love to see more of those.
You bring up an interesting point, and now I’m wondering: how would a gaming-focused phone sell in a post-Switch world? We all remember the Xperia Play, but maybe it was just too early. What if Apple released an “Arcade edition” of the next iPhone for $1000, which featured a slide out controller or some other slick integration of physical controls? How well would that sell, and what impact (if any) would it have on Switch/Steam Deck sales?
I mean, Asus and nubia have been making a gaming-specific phone for many generations now. Razer even gave it a try back in 2018, but I don’t think they released any follow up devices.
Lenovo also made a couple devices, but announced earlier this year that they’d be discontinuing their gaming phone business.
There seems to be a fan base and market for gaming-specific phones, but given Lenovo and Razer got out of the game and the fact that you haven’t seemed to have heard of any of these devices/product lines: my guess is that they are super niche.
I appreciate the links and examples, but none of those has physical gaming controls like I was suggesting. Obviously high end hardware is important in a device like this, but the physical controls were my key point.
