It also doesn't seem obvious that using one's less dominant hand for movement is optimal. Kind of like playing guitar. As a righty who go my start trying to learn solos, I always felt like the left hand had the harder job.

You can get used to a game controller, or well, most of us do eventually. At anyrate, you can find left handed game controllers on the market.

But that is a crank, it requires a bit more dexterity, like holding a pen.

That crank better be detachable in a slick way that keeps it from inadvertently popping out constantly or it's going to annoy the hell out of anyone who isn't a hardcore fan of the crank-based game genre. IRL it's probably not detachable and it's going to jangle around and annoy while gradually self-desructing in a way that leaves it useless yet permanently attached/annoying.

It folds into the side. That's why there's a hole.

My ps4 allows me to remap keys and it’s a blessing.
