To clarify, I am skeptical that the hardware was picked specifically because it was the optimum one for the game. I think it was picked because they had it around.
Many Arcade companies made their own controller devices from Scratch. Such as the Hard Drivin Shifter, wheel, and pedal sets. Discs of Tron Spinner. Pole Position wheel & shifter. Sega Turbo geared wheel + 4 position optical pedal set, 4" Diameter trackball on X O Football / Missile Command... and much more.
In fact, Marble Madness creators were originally trying to make a motorized force-feedback trackball set. Unfortunately, they couldnt get it to work right & ran out of time... so used the standard design instead.
Back in those days, it wasnt about being generic carbon-copy and cheap. It was about making games that were optimized to the Player experience, Breaking technical ground, And pushing the limits on hardware & programming to the maximum. Games were far better balanced, and challenging, as they actually spend a Lot of dedicated time to make games Play better.
were more concerned with catering to operators and distributors than they were to actual gamers and the gaming experience.
Furthest from reality of the 80s to early/mid 90s. Thats more of the Modern attitude, and the reason why the arcades Sunk.
And furthermore, the Arcade designers didnt care much about catering to the Ops much at all. Try to find and then read coin meters on 20 games in a row. They are all over the place. Some, in places that are very hard to get at or read. Some cabs are a nightmare to work on and get at components. I could go on and on. Games were designed to appeal to the players.. as the players happiness meant more earnings and sales. End Of Line.
Generic controllers came as a means of convenience. A company producing mass amounts of controls & parts for cheap, with good quality.
Also, when certain designs were proven effective, they had no need to be re-invented / re-designed / custom built. IE, the standard Trackball design has never really changed much.
Leafs have some Excellent properties... but, they were somewhat unreliable as they can get out of whack over time.. and they need to be kept cleaned. However, games like Galaga or Asteriods Deluxe still play better with Leafs, as you can activate the button with a light touch, not needing to Clash the button all the way down (less player fatigue & faster shoots). And leaf sticks were actually more durable, compared to the earlier microswitch designs. (Happ Ultimates eat through spacers in a matter of a few months)
I was more shocked at the P360 comment re fighters since that is what MKII cabs came with from what I recalled.
Doubtful... and even if it was so, they were probably taken out really quickly when they failed.
I worked for Time Out, both before and after the Namco buyout. NONE of the fighters had the 360 in them. Not in ANY of the 3 locations in my city, nor as far as Ive heard & seen, in any arcade owned by Namco. (many stores swapped games often, and Namco owned a good deal of the Mall arcade stores)
All the new fighters, and even many older titles, used Happs Comps. A limited few had supers.
Optical sticks are expensive (hence they were Not in most arcades), and optics have and can do fail just like anything else. And when they fail, its much more of a pain and expense, to deal with it. A micro can be swapped in a minute or so, depending on crimp -vs- soldered terminals.
One thing about Leaf sticks.. is that you can use them on such a way that you rarely bottom them out. Meaning, you never really smash the stick into the edges of the mechanism.. and even if you do, most of the forces are very dull due to the rubber grommet, the leaf springs themselves, and the way things are assembled. Every time you jolt on other controllers.. it adds up to a certain level of stress fatigue. Where as leaf controls are more 'floaty' and can be used for longer duration with less discomfort.
I have not used a 360, so I cant comment about how they feel and react. I do however know the Wico Leafs, Comps, and many others to which to compare with... and nothing Ive used works better for classics like Robotron than the Wico leaf sticks... even if they are more of a pain to maintain / adjust every so often.
