Thank you for reminding me of The Incredible Machine! I am going to add its two sequels that most people have never heard of, TIM: Contraptions (essentially a HD re-release of the first game in a new engine.) and TIM: Even More e Contraptions (What would now be sold as DLC.)
As of right now, it's still there and still showing in Hot
