I assume the Mad Catz sticks/pads are in the OT because they released about the same time the game did.
There are so many sticks/pads out there that adding more might clutter it up.
A simple link wouldn't have taken more place and was denied. When there is a consensus on the Fighting Commanders over the Madcatz pad from the beginning in those threads when players asked pad advice, I really asked myself some questions.
