It’s very common. Quake, as one example requires a number of simultaneous key presses for it’s movement tech. Another I just tested out is Infernax, an old-school style metroidvania. With a controller I had no problem holding the forward and jump buttons, and then hitting the attack button. If I do that with the keyboard, the character won’t attack. And to make sure it wasn’t just that game, I loaded up Timespinner to try the same thing. If I hold forward and jump, they won’t attack. Although curiously if I hold up and jump, they will attack, so I suspect it has to do with forward/back (a or d), jump (j), and attack (h) all being on the same row.
I’m honestly amazed there isn’t a company out there making making premium aftermarket laptop keyboard upgrades, including with features like key rollover. Anyone jumping on this first would have zero competition (at least for now).
Looks like there is at least one mechanical chiclet keyboard out there.
