I anybody needs this, I have the new MacBook Air with the M1 chip and I'm running Big Sur on it. Could that be the reason? That I bought them when I could still play them on Mac? Or is there something else? And could I possibly do the same with some other games? Maybe I couldn't play LEGO Lord of the Rings because it is way too old, but a newer one might still run on my laptop, like LEGO City Undercover or LEGO The Hobbit? I don't know. Super Space Club is an arcade-style space shooting game about pilots. However, I'm still able to run the two games which I bought before Mac stopped supporting 32 bit games (the other one being LEGO Star Wars: The Force Awakens). LEGO Marvel Super Heroes features an original story crossing the entire Marvel.
There are only a few LEGO games that are playable on Mac, which is disappointing. An epic blockbuster action-RPG featuring Super Heroes and Villains from the Marvel Universe The Avengers, Guardians of the Galaxy, Inhumans, Defenders. Thinking that I'd be able to do the same with another game, I bought LEGO Lord of the Rings and couldn't download it to my MacBook Air.
I downloaded and ran Lego Marvel's Avengers successfully, which I had already bought on Steam years ago, even though it is not supposed to run on Mac anymore. I recently decided to revisit some old games I used to play.
