On a stick, each movement takes a move forward then a move back to center to stop walking off the cliff. It takes twice as many finger movements to get the same action.
You must live in a world without auto-centering sticks. There's no need to "move back", not even taking into account the ability to move slowly in the first place. And how is it twice as many movements when you say " tap the forward key very quickly."
Besides, the thumb is your most cabable finger.
I understand that the sticks are technically analog
Not technically analog, they ARE analog
and you should be able to slowly creep forward, but their response is so bad and the range of motion is little that it is quite difficult to move just enough to creep forward,
Your thumb is quite cable of making tiny movements. Now admittedly as a PC gamer you haven't got the skills/practice to do it well, but it's quite easy actually. Just because the stereotypical "ham fisted PC gamer who hasn't touched a joystick since 1981" can't do it, doesn't mean that it's a problem for anyone else.
That is also why headshots are impossible with stick and the games have to help out with aim-cheats.
Stop right there. I wasn't talking about FPS aiming now was I. I was talking solely about movement. The mouse is a fine pointing device, but it is essentially "easy mode", which is why you like it. In the transition to mouse aiming, mouse aiming was considered "easy mode for casual dudebros" compared to the games that came before it.
Headshots shouldn't be easy if we have any pretense towards realism in games, they should be HARD and rare.
The stick moves when you move it over, and keeps moving even though the stick is still, you need to move it back to center to stop the movement.
You're doing it wrong. "You" don't move it back to center. it moves itself back to center.
The stick also has a maximum speed that is way slower than mouse movement.
It depends on the game settings. What, you didn't know you could change the speed of the right stick?
With a quick jerk of the hand you can do a 180 spin. On a stick it is move over, wait, wait, wait until you have moved a full 180, then move back to center. Way too slow.
Again, you're doing it wrong. You don't move it back, it moves itself back.
