The director of Raiders of the Lost Ark, E.T., Jurassic Park, and many more classics has long spoken about his love of video games, stretching back to 1982 when he revealed the instant thrill and ego “massage” that playing games like Donkey Kong and Tempest provided.
Analog sticks beat WSAD for movement any day and the mouse beats analog sticks in aiming.
Different tools for the job.
There are keyboards with hall-effect/magnetic switches that allow precise measurement of how much any given key is held down. With that said it’s be possible to map the signals from WASD to emulate a controller’s left stick (at least in games that allow simultaneous kb+m and controller inputs, but that’s fairly common in my experience).
I have a keyboard like that on pre-order and I’m definitely looking forward to trying it. 4mm of travel isn’t much, but it should still be better than a binary signal.
