Once uppon a time, somone in those teams used those joysticks for their games. Then that person gave them to the team because they were not being used.

You can't buy analog joysticks because mostly all today's joysticks are USB.
There is an adapter for USB joysticks but they are very expensive for whatever reason.

You may find some analog joysticks on e-bay if you search hard enough.

Happy Hunting!!!
