People who play fighting games competitively accept that sometimes their ferocious and constant play will result in a few broken controllers, but the last thing a player would want is for their stick to break during the final of the video game industry's biggest competition.
That's what happened to Momochi (as Evil Ryu) during his grand final match against Gamerbee (as Adon), but the disruption wasn't enough to put him off. Mid-match the game paused itself as the controller failed, drawing shocks from the crowd in Las Vegas.
The rules (in full below) state that if the game is stopped in any way then whoever stopped it must forfeit the round. Gamerbee took that second round (but in a show of sportsmanship let the time run down) as a replacement stick was found for Momochi.
This left them with a round apiece, leading to a third and final round after a gruelling wait. With a new controller Momochi was able to triumph, winning the tournament and $33,000 (£21,000, €30) in prize money.
