I'm with rct-uwe1 and wowman, it almost seems as though they had planned more gentle/kids rides, yet never got to them. Also, kids rides where the kids ride, and parents wait, (that might be too hard to program). Game booths might be fun.
As long as we're dreaming, I know we got some "vintage" rides, but I for one would love an "antique" ride collection, including walk through attractions, such as fun houses, Noah's Arks, and dark walk throughs, mini golf and mazes, some animal rides, elephants, camels, and ponies, and of course some really old rides like a witching waves, captured airships, etc. You know, like when I was a young man.
Perhaps they could create a simple to use ride maker? You can choose from a couple dozen ride cars, and create your own spin and pukes? Elehants, rockets, magic carpets, generic cars, teddy bears, etc. etc. etc.
And a fix to the AI, where once a peep picks a destination, they actually go there, instead of getting three quarters of the way, then changing their destination back to the other end of the park, only to reverse yet again and head all the way back to the other side of the park. And being hungry or thirsty or needing the latrine, yet walking by a bunch of them to get to one on the far side of the park, and again reversing direction and going back where they started.
Finally, of course, my stadium attractions!!!!!!!
