Although not directly related to Namco's fighting games, it is definitely relevant to everyone's interests. Lab Zero games have managed to include the drivers for PS3 compatible arcade sticks with the PS4 version of the game and thus saving gamers 100's of dollars from investing in PS4 specific arcade sticks. Fans of Tekken 7 will be facing the same dilemma once the game hits PS4 eventually. Now that everyone knows it's possible and Lab Zero is offering the drivers for free to any developer that wants to use it, you all know who to talk to make sure this feature will be in T7. More quotes from the developer below courtesy of Polygon.
EDIT: Recently it's come to light that Lab Zero weren't solely responsible for the creation of the driver, it was a collaboration between Lab Zero and Naughty Dog.
