If you could successfully make the argument of, o sure, we have the same idea as asteroids, but our version is a completely different expression of that idea, then i think you could follow into the category meteors ultimately fell into. Cause otherwise, the maze chase games, whichever one came first, would be able to claim copyright infringement on all the others. It wouldn't matter if the design was a car instead of a gob because you're saying, well, it's exact same experience. And ultimately, law is something that people have made, so therefore it is going to have the same sort of limitations and failings as people.
