We can add a note to pub description saying "Make sure to check out the previous iteration too, it's really good".
As for creativity,
in this presentation Mick Gordon talks a lot about how innovation requires a certain environment to blossom: an environment where one feels
comfortable with failure. Creative evolution is like brainstorming: weird ideas are being thrown around, some of them are silly, some of them are funny, some of them are dumb, but instead of frowning upon them, everyone just keeps inventing, and in the end something truly amazing may get born.
This means that having a new run obsolete the old one despite the fact that the new one is not obviously better in all aspects, helps the author determine what made the original one good, and what is missing in the new one. And this in turn helps the author make an even better playaround in the future!
Of course I don't know how much potential a game can have for several truly innovative playarounds each of them having a lot of surprises. But the overall mood would be much more inspiring if we had a room for "imperfect" attempts.
