TTT2. It was the one objective flop in Tekken's history and Bamco are scared shitless of it happening again to the point where going back to "basic" Tekken is death in their eyes. That's why we get tryhard-as-fuck newcomers like Fahk, Victor, and Leroy over Christie, Bruce, Mokujin etc. and why we have dopamine bullshit over actual fundamentals, stepping, and all the shit the series once lived by.
