I still need one more vote to break the tie for the next park, and no one suggested any challenges yet. VVVVVV is over now, so I can focus on Adventures of Lolo and Roller Coaster Tycoon.
I think I'll make a "poll" here, then, so people can decide.
Choose between the three, and give a challenge for me
>Dusty Dunes (A Desert With Slopes and Hills | It already has a pre-built coaster | Goal: Guests by Year 3)
Temporary Challenge: Do not make any changes to the landscape. Don't build any supports (as in, every single part of every single ride must be touching the land.)
>Leafy Lake (A huge field with a lake on middle | Empty at beginning | Goal: Guests by Year 3)
Temporary Challenge: Do not build ANYTHING outside/inside the lake. (one of the two)
>Bumbly Beach (A park near the beach. Small terrain, can make tracked rides above the ocean | comes with a Coaster, Merry-Go-Round, Ferris Wheel | Goal: Guests by Year 2)
Temporary Challenge: Turn the park into an ocean. Charge for entrance and food things. Lower 1$ Entrance Fee for each square not covered by water.
I really like the challenge in Bumbly Beach, although it seems it could be hard as hell. So, vote which park you would like to see, and you can suggest new challenges for the parks. I might change which challenge I'll do, or add another point to the challenge.
So yeah, vote.

EDIT: Also, should I make a thread for ALL my LPs? Because I plan to a lot more, and I wouldn't like to make tons of topics.
