Before I start, yes you can use a controller with most of what you will find on Steam, and with some cel games. But this is the major point.
I was raised around a few concepts, I had a father who studied a few martial arts (I won’t say anything I have), and a mother who was a dance instructor, student and ballet performer with some Jazz, et al…. under her belt. Also she had a Yoga Instructor history as well.
Now, what these things teach in a way of common fundamental are palms up, a full lotus adds foot bottoms up too (I will say I can do this). Basically energy leaves your body in a way that is less of a pain this way. Like with a punch, it always starts palms up, and impact is down. Guess you release the bad energy, grapple some good, and the hit makes it bad and you go back and release it again.
I wish I could type palms up. That would make this a whole lot easier.
So when I say, a controller, more commonly used by the console gamer, is the best.
Usually with PCs we have an image of a Golem type guy hunched at a keyboard and typing away. I always hated using a Keyboard as with touch screen and now I see why.
The console way is palms up. Arcades were palms down, but it got you out. Now we have 3ds which inspires out-going with Street Pass and Pedometer Coin rewards use in many games, perhaps under used. Nintendo was largely the brightest of companies in designing even for the biggest of hands. Even had an RPG controller for Super Nintendo in Japan (Super Famicom). Wish they still used that model.
Basically with something like the RPG controller you’d sit back with a palm up and relax in play. To an extent the Wii and Switch controls are like that (separated the latter machine is no good for huge hands) and the Wii U Pad was ideal for dual palm up play with big hands especially. Worst design I would place on Microsoft, who knows why.
Point being, if anyone tells you it’s wiser to play something endlessly palms down, they need to re-examine.
