I've not played the PC version in about 7 years, but from the short time I've played, it seems a pretty solid port. Lots of ride customisation, entrance/exit, colours/types, music choices, you can't add your own from what I can see. Lots of in depth data and what not on rides, stalls, shops etc.
I only have 5 rides and a few stalls and shops but it's running beautifully on my 6 plus. You can zoom in to each individual customer and then waaaay out to view your entire Park, no half arsed zoom like some games use. You can of course take a ride on any of your attractions.
Like I said, Ive not played the PC version for 7 years, possibly more, but it seems to have a lot more customisations than I can remember. Really impressed so far.
