This game made me fall in love with the Tycoon genre.
There is something tranquil and mesmerizing about building your park piece by piece, watching guests enjoy your rides, which you carefully built to fit in the scenarios to look pretty.

Setting up prices to your rides, shops, hell, even bathrooms but don't do that .
And watching that $ balance go up.
Keeping your park clean, raising your janitors salary to keep them happy.
Hire mascots, that fit in with your park's theme.

This and more; one of the best Tycoon games ever made, coupled with the Wild! and Soaked! expansions, which add respectively the ability to make zoos and aquaparks... it just never stops giving.
