don't agree. Every time I had 4 or more people playing, players 3/4 always stand at an angle. When they push up, they go up. Again, you can always order the control panel without button/joystick holes at all. I suppose right/wrong is up to the owner to decide. In any case, it totally makes sense to me and everyone else that has played on it.
Every Arcade Machine that has 3 to 4 players... always has Straight Joystick alignment (all sticks mounted the exact same angle).
Just because you might Stand at an Angle... does not mean that your brain things Up is in the direction that you are facing.
Imagine playing a game.. using a Gamepad... sitting 45 degrees from the screen.. due to sitting on the far end of an L-Shaped Sofa.
The Gamepads "UP" is always UP... NOT "Diagonally Towards the Screen".
Its often not as bad, when you are playing a Beat-Em-Up, like TMNT.. because you are constantly walking in
various directions (constantly affirming positions)... AND, because these games are not that Critical about making
a Directional mistake.
If the two angled people tried to play a fighting game like Tekken 3.. they would certainly make constant
critical directional mistakes.
This is a Gauntlet Control Panel. It was probably one of the First few games to have 4 players on a standard
non-driving Cabinet.

Notice the words "UP" above each stick. Realize that only two people could fit against the front of this Cabinet..
and the two others, stood against the left and right sides of the control panel.
Despite this being Super Cramped (especially compared to later 4 player control panels), this worked just
fine. Atari would have Angled the sticks, to give the players more comfort... if that would have worked out.
However... Loads of actual Play-Testing reveals that angles sticks, are always a bad idea.
This is the Simpsons Control Panel. Notice the Shiny Carriage Bolts, that hold the Joysticks to the panel? They
are all mounted the same direction... not angled. The only thing they angled, was the Buttons.
