It's silly to act like COVID didn't dampen the Runaway Railway opening. By the time it opened on March 4, 2020, COVID was dominating the daily news cycle, conventions in Orlando had begun to be canceled, and international travel had already slowed considerably. Sure, people were still in the parks, but go back and listen to any theme park podcast from that week and most of the talk will be about COVID -- and that was before the parks shut down on March 15. If no one is talking about a ride opening a week later, yeah, that's gonna dampen enthusiasm.
Does any of that matter for Disneyland's version? I'd say no. It's still a cloned ride that big fans could've ridden in Florida for years and it lacks the must-see factor of Rise. Mickey Mouse is popular, but he's also ubiquitous in Disney parks without ever having a real ride. Nintendo is much fresher. I don't see Runaway Railway besting Mario Kart or SNW as a whole in terms of hype.
