I just bought RCT2 off Steam a couple of days ago and paired it with OpenRCT2. All good.
I wanted to do the WW scenario 'Asia - Great Wall of China' in which you have to raise and keep the park rating to 800+ with money not being an object.
After several of my own (quickly) failed attempts I found a girl on youtube doing this exact scenario, but even though I tried copying her approach (which worked..) still 0 guests was arriving at my park, obviously failing the objective.
So, there's clearly some bug afoot here - How do I solve this problem?
