Valve did a bit of a woops here, as they recently accidentally leaked the designs for what looks like their upcoming Steam Controller 2 and a new VR controller that is likely to come with the long leaked Deckard VR headset.
It looks like the inbred cousin of the Xbox "Duke" that ended up being surprisingly ergonomical. This may be an unpopular opinion, but I genuinely hope it's something close to that. Most controllers are too small for me.
It'd be cool if controllers could just be adjustable size. Hand sizes are wild. My fingers are pretty short; my best friend has E.T. length fingers. We are otherwise about the same height and build.
Duke? Is that the Xbox 1 pad? Because I actually loved that. It's a chunker but was very comfortable for my larger hands. Reminded me a lot about the Dreamcast gamepads.
Well the joy-cons kinda do that but if you wanted something that's actually adult sized you'd have to check 3rd party options and there's probably no guarantee that it will work on anything other than the Switch.
All I hope for is that the Controller fits well in my long thin hands - like the fat Steam Controller does.
With the right joystick in place, it's certainly a product I may buy. The Steam Controller trackpad was not a sufficient alternative for joystick input when most games designed input with the right joystick in mind. Aiming and camera control with a variable and non-tactile deadzone and input default of trackpad camera controls has always been annoying to me.
Offtopic story:
Sometime ago I needed 2 gamepads. So I went to the mall and bought 2 Acer gamepads for 35€ each. I unboxed them right after I left the shop. They were wired and looked and felt exactly like 5€ chinese gamepads. So I immediately returned them and went to another shop in the same mall where I got a pair of Speedlink Rait controllers for 22€ each. They feel very well-built, just like an xbox controller and are supported by all OS and console emulators out of the box. It basically shows up as a Switch Pro controller, so it's perfectly supported by Yuzu.
