Pontifex

Build your bridge with love. Be proud of your creation, and give it a pompous name. Then eventually watch it with horror collapsing as a train runs of it, giving you an undeniable proof that your bridge was indeed flawed. Then start over.

These few sentences depict well a typical game of Pontifex, the successor of the infamous freeware Bridge Builder which had already made crazy numerous players around the world when it was released.
