I've never seen a list, and I've been playing over 2 years (finished the game in Sep). Would be helpful for players who haven't finished to get access to one. I recall it gets to a point where you need about 100 per scene within the same chapter, and about 150 or so to contribute to opening a new chapter (in addition to completing the previous chapter's end puzzle and getting a flight crew).
The help requests in your Inbox are for you to be part of a friend's flight crew. As soon as you answer the message, your part is done.
But when it's time for YOU to open a new chapter, you'll be taken to a page showing you all the requirements you must meet. Flight Crew is the last one on the right, and it has a "hire friends" option, which opens your Friends roster. Usually, the first friends shown are also players of the game.
This roster naturally chooses everyone right away, including friends who are not players. To avoid those friends getting cranky about receiving help requests, click "Unselect All" in the bottom right corner. Once you do that, you can check only those friends you want to help you. Once three of them respond, as you did with those in your Inbox, you will see that you can "travel" when you start to play again.
If, after 18 to 24 hrs since your request (can't recall how long), you see that you're still short on "crew," you can request new freinds to help.
I don't have that option coming up on my screen. All I get is the two boxes in the centre with "unlock next chapter" one is marked complete, the other is waiting for me to get enough prestiege points. There isn't anything else. Travel now is greyed out because I don't have the right amount of points.
Yes, it is usually a 3-part process: chapter completion, prestige points and flight crew. Oh-that box on the bottom right isn't called "Unselect All" - it's called "Select None." Sorry about that.
Don't forget to limit your purchases to items with high-point value. You don't want to run out of room on your island before you finish the game. Once you do finish, then you can sell any repeat decorations for half price and start decorating the way you want. You can also replay the game in a kind of Relaxed Mode (no worries about prestige points or hiring a flight crew).
Have received a reply from another player :) :) :)
I have not seen a list and did not pay attention earlier in the game. Now that I am further along and play has slowed down I noticed the following...
Each new chapter requires 500 points more than the previous, in multiples of 500, The first scene opens at the chapter minimum. Scene two requires 50 addition points than the chapter minimum. Scene three requires 150 more points than the chapter minimum. Scene four requires 250 more points than the chapter minimum. And scene 5 requires 350 points more than the chapter minimum. The challenge scene at the end of the chapter requires 20 badges (out of a possible 25) plus all 5 scenes played at least once, Finally, in order to travel to the next chapter, you need 150 points more than what was required for scene 5 (which is 500 points more than the current chapter minimum).
