I enjoyed The Incredible Machine as a kid, the modern equivalent (though still 10 years old) is 'Contraption Maker' - https://store.steampowered.com/app/241240/Contraption_Maker/ - which was designed by the same person. Glad to see he's still going all these years later!
This is not 'Incredible Machine' related, but while I'm here, I'm working on an engineering-adjacent game where you build and automate a zoo full of spooky monsters. Might be of interest to some! https://store.steampowered.com/app/654960/The_Eldritch_Zooke...
