The underground pipes connect to underground connector of the big Deliveries Building, which can usually be found near the park entrance (just like in the tutorial).
I guess I'll try it again. I tried moving the pipe to that building (from one of those garbage collectors) but it stil said not connected. I guess I need to find the exact tile to connect it to?
In the tutorial it highlighted where I need to place the pipes, so it was easy. Maybe an indicator where the pipe need to end up would help.
Keep an eye on the thoughts of your guests - if they think something was a good deal you can easily increase prices without annoying them.
Yes, I'm already doing that. On that first after-tutorial scenario, I build all the available attractions and raised the prize on them until people no longer said it's a good deal (btw, for fruit juice I had people both say it's a good deal and that it is too expensive at the same time). I got 200 visitors in the first year, so I got the optional goal, still my income was only +50/month (no research yet). The default researching already costs 600/month and I wanted to hire a few more employees too to fight vandalism, so I quickly went down to -650/month from there.
By the way, is it smart to have both an entrance price and a price for the attractions? I know that in RCT if you put an entry price, then the attraction price would default to 0, but in Parkitect it did not. It kinda encourages removing the entry price because it's less work than setting it to 0 for everything you build.
Anyway, I'll keep on playing and see if I can improve further. :-)
It's nice to see that you're still active on here. Thanks for the reply!
