Actually, behind the cut I'm going to skip details about the major plotlines (or even mentioning most of them), but expect that in comments, and there will be smaller-scale spoilers.
So I have done a lot, but there are still some things I can't figure out!
Here are the three things that come to mind:
I'm pretty sure you can't save the woman in Brisbane, because I've tried all the permutations; I can't get the maid to give me her letter (which would tell me that the newspaper offices are in town), and I can't keep the well-meaning bystanders from taking the notice. I suppose there might be something I could carry or show the maid to convince her (maybe Goland's family heirloom)? Anyone managed it?
There is also a mysterious woman in the bar car on some legs of the Orient Express, who vanishes (along with the whole bar car) the next day. I've met her on the way from Paris to Venice and the way from Venice to Istanbul, and I have no clue what's up with that. (Edit: wait, is she maybe one of the people you can meet in Istanbul if you go to Belgrade? The problem is I don't think you can do both of those in the same trip, I think the timing is wrong.) (Edit 2: no, you can't get to Belgrade if you go to Vienna first.)
(Edit 3: and what about Mount Elbrus?! I just went past it last night and with hints like that there has to be a way to get there and see what's going on!)
And is there a way to get to the south-eastern parts of South America? I mean, the US cities that you can't get to, you at least pass through, but I haven't been able figure out how to get to any of those (Salvador, Rio de Janeiro, Asuncion, and Buenos Aires).
I have definitely not been everywhere, of course! But I've at least passed through a LOT of places, and looking at the map, the south-eastern parts of South America are the only region I definitely haven't been to.
(As an aside: doing the North Pole early gave me an entirely erroneous view of the jeopardy I could be placed in the rest of the trip, since it is the only place you can die!)
What's your favorite unexpected connection or small-scale story? (I'm assuming most people have found the big-scale stories. If not: the further off the beaten path you go, the wackier things get; which is another reason I'm wondering about those four cities in South America.) Mine was discovering that the warehouse in Antalya, where you're forced to pretend to be their employer and find Venetian glass, actually has a story behind if: if you go through Athens you can meet the actual owner and get a mission from him. And then if you rescue the woman from Alexandria, they turn out to be connected! (I really like her, probably because the science is so daft).
What's the thing you're proudest of finding out, or most interested to find out if it can be done, or favorite character? Just, gossip with me, people!
Edit: hi, anyone coming here from Meg Jayanth's retweet! If you don't usually use Dreamwidth, just know that (a) if you don't have an account, you can choose the "Anonymous" radio button, but (b) PLEASE sign a name or nickname or something so we can keep each other all straight, okay? Thanks!
PS: I totally broke the game today, I got stuck in Quetta with no Fogg and no money and no way to go anywhere, it was hilarious. (Email to the developers already sent.)
