Rollercoaster Tycoon had many small game elements, like this one, that could be played with and expanded upon to the extreme. A lot like GTA, while playing the game in the intended way is fun, you could also spend hours on doing things the game designers may not even have thought of. I remember my friends and I would set up a target, like a pool of water, and then build roller coasters that would end abruptly and launch the cars flying into the air, the goal being to hit the target upon crash landing.

Apparently I'm not the only one who just enjoyed crashing stuff and torturing the guests in the park:
