Yakuza 0 finally came to PC today, with full mouse and keyboard support. But thats not how you want to play a hardcore Japanese crime game. Nah, PC inputs are for suckers. At least, thats what Sega wants you to think, since theres a giant splash image when you launch the game reminding you that real yakuza use a gamepad – not mouse and keyboard.
