Hey. I come from THUG2 / THAW park making background and I find editor in THPS 1+2 amazing. It still could be improved here and there, but overall it's great.
I made a park recently which took a bit of my time, but it's ready, so you can play it yourself if you own the game.
I made a presentation video about the park, but I didn't show everything, so you can explore yourself
