For the last few months I have been working on a build that is supposed to be my version of Central Park with high-rise apartments, restaurants, shops etc.
(I did this same type of build in RCT-2 years ago.)
The idea here is to use as much in-game scenery as possible, those skyscrapers really stack up the files!
This is a test run I stuffed with rides to see how the park fared, how much headroom if any I had before my system locked up... we are topping out at about 3500 guests and are running okay.
At first I had some pretty elaborate coasters in place, but I did have to lose a few of them because my system bogged down.
So, I'm trying to do as many easy and "passive" attractions as possible, here we have the custom aquarium, the 9-hole miniature golf course and the hydroponic garden in the lower-left corner...
On the other side we have a large municipal pool and a park favorite, the lion exhibit, which makes a ton of money for the park, we both charge admission and sell the cubs for big bucks!
Overall, I believe I have enough headroom to add quite a few more buildings, so it's back to filling up that skyline!
It needs more shrubbery, more attention to all those details, but it's a fair start.
