I've had an idea, inspired by another thread.
You are challenged too design an amazing theme park around a particular...well...theme.
What would draw people in? What would make it unique? What would it offer to people? What is your selling point? What location would you choose?
You budget is pretty much inexhaustible, so let your imagination run wild!
Are you looking to design a Twin Peaks style park? Silent Hill perhaps? Wild West? Medieval? Zombies?
