RCT2 is much better then one, number 3 is a completely different game but its still epic fun, I should upload my Roller-coaster "The Bone Crusher". Oh yeah if you're making a pool with the expansion I think it is you make a water slide 10,000 feet above ground and add a small pool at the bottom and people ride it and fall 10,00 feet and land in the water 100% fine, it so funny watching children doing back flips and flying out of control.
