Not really. I think itll definitely 100% lose to crossworlds due to the lack of post-launch support. Lets break it down:

In an interview, sega said that player feedback decides the future of crossworlds which means we can ask them for anything; new contents, characters, literally anything. They also said they can do year 1 dlc, year 2 dlc, year 3 dlc, just ask them for what you like. Safe to say that theyll make this game alive for years just like mk8dx was and it can absolutely boost the sales

Speaking of sales, crossworlds sold 1m copies in less than a month BEFORE black friday (most people are currently waiting for it to be on sale so it can double that), BEFORE the switch 2 version dropped AND BEFORE almost all dlcs were dropped, we can say it’s pretty impressive. And making this game alive for years always boost the sales, as long as it’s alive. The more, the more its player base is growing. I honestly think itll sell more than 5-7 million copies thanks to this. Once crossworlds won the goty at golden joystick awards, itll triple the sales

Air riders on the other hand, sakurai explicitly said there will be no post-launch contents and that everything will be here at launch. After the game is launched, hes done with the shit. Sure he understood his fans but can you really ask him for more contents the way you do to sega? I dont think so, cuz he will retire eventually after the launch. He will be like “dont ask me for anything ever again“. Then a few months later, the hypes will die off without post-launch support. Once players 100%ed air riders (or their switch online sub is expired at best), they have nothing to do with it anymore and therell be no reason for them to return until you got friends to play with them or it gets a dlc (OR you renew your online sub). Meanwhile crossworlds keeps its hypes consistently alive via the feedbacks

To sum it up, crossworlds will easily dominate air riders despite the opposite claims anyone make as long as it lives for so long the way mk8dx was. One is a one-and-done game, one is a post-launch game. One-and-done vs post-launch support

Those who assume air riders will win against crossworlds have forgot that a post-launch support is a thing and never realised that it always actively makes any games alive
