Described as the fight the fans asked for by the executives who made it happen, Sunday's clash between Floyd Mayweather and Conor McGregor was only ever about one thing - money.
Having beaten the Irish pretender with a 10th-round technical knockout, Mayweather can retire with a perfect 50-0 record and a payday said to be worth up to US$300million, and the American has promised never to return to the ring.
McGregor, however, is a different story.
His $30-million purse for the fight is 10 times his previous best disclosed purse from the Ultimate Fighting Championship (UFC), where, as he says, he endures "shinbones to the head" as he makes his living.
In the altogether more genteel surroundings of the boxing ring, he made a lot more money with a lot less damage, and his appetite has surely been whetted by the enormous riches on offer.
McGregor has made no secret of his desire for more.
Asked what he liked most about his boxing experience, "Money" Mayweather prompted UFC lightweight champion McGregor to say the cash.
"The cheque is alright. The cheque is not bad," the Irishman laughed as he sipped his own "Notorius"-brand whiskey on the podium of the post-fight media conference.
"I've already been raising the MMA (mixed martial arts) cheques. I'm still going to be raising the MMA cheques when I go back there," he added.
The 29-year-old has started his own website, a clothing line and a number of other businesses, and he was clearly delighted to see the logo of his latest venture, McGregor Sports and Entertainment, in the ring at Sunday's fight.
It's unlikely to be the last we see of it, too, when he returns to the ring in the future.
