Scroll-Keeper, Keys to the Gems
The senior CMs will tell you that no event is designed to be completed by a brand new city, they are very well aware of this. A pop up city can use an event to begin collecting instants, spells and such, but some quests will take a couple of days .I started a new account on a different world just to see what the event was like for a brand-new city that entered partway through. Of course my experience is not the same as a truly new player because I've learned a little about the game while I've been here. But I have some immediate feedback about the first few quests.
1. Buy 4 KP. This quest works. A new city has enough coins to buy that initial 4 KP. Might cause some building constraints though.
2. Collect Coins. The coin amount for a new city is 1000. This is not unreasonable, but it might help to have a tip that you can gain coins through visiting neighbors as well as collecting from residences. This would get people into the habit of giving neighborly help and help them progress further.
3. Beverages x 8 Perfect. Making beverages is a natural fit for new players.
4. Spend 4 KP Not bad. At worst the person is going to have to wait 4 hours for more KP.
5a. Use 2 Enchantments This is where you get a major hiccup. A new player doesn't have a Magic Academy for at least the first 2-3 days unless they are using diamonds or being very aggressive about exploring the map, and even when they do they can't make enchantments (although I think the MA comes with some enchantments?). You can get enchantments from doing neighborly visits, so it's not impossible, but it's random. My character was pretty lucky and got an MM and an ensorcelled endowment. Building a factory is pretty easy, but I won't have anything to use an EE on for a while. I suggest that an MM and a PoP should be given as a reward for completing one of the first 4 quests. That would allow a new player to move ahead pretty smoothly through at least quest 12 where they need more enchantments (which they could probably get from neighborly visits). Alternatively, you could make spells like MMs and PoP a lot more common in the event chests, but you might not want other players to get them quite so frequently (as awesome as that would be).
I am not saying that a completely new player should be able to finish the event easily or even get very far, but if you are presenting quests to players in their first several hours of gameplay that they can only accomplish with the right amount of luck, I think that will result in frustration.
Where are you playing now? I'm on Winyandor and Harandar.
