Pathfinder Adventure: Troubles in Otari

Where are you getting a $99 price tag?

This definitely needs a Foundry VTT module!

I would love to see the full Foundry experience of Beginner’s Box (Menace under Otari) > Troubles in Otari > Abomination Vaults.

Is there a Player's Guide for Troubles in Otari?

There is a Player's Guide for Beginner's Box and one for Abomination Vaults. We are planning on running BB -> Troubles -> Vaults.

So would I just give them the BB and Vaults player's guide?

ALSO ... is BB, Troubles, and Vaults already remastered compatible?
I was reading through all the previous posts here and I saw people were asking for a deluxe beginners box that included troubles. Maybe one using remastered rules :)

A reprint of the Beginner's Box is coming for remastered rules. I do not believe that it will contain Troubles. There is no planned update for Abomination Vaults. Troubles itself does not have a player's guide as it is part of the standalone adventure line that does not get player's guides.

I would actually love to see mini-players guides for the stand alone adventures. Especially the 1st level ones, where a couple of backgrounds tied to the module would be cool, but even for the higher level ones a few pages of what to expect would be nice.

Updates to older adventures for the remaster don't really seem necessary. Changes are generally minor enough to not be a big deal, so it would be a lot of work for little benefit.

TBF, while it can be played with "full rules" and by itself, Troubles is a direct sequel to the beginner box adventure, so doesn't really need it's own player guide. It also use the Beginner Box modified rules by default (like simplified poisons), and is exclusively using creatures and items that can be found in the box, no need to have any other books.
The "player guide" for the Beginner Box is mostly having premade characters wholesales. There's a limited amount of rules to create custome ones, but the options are very limited to slight variations of the pregens as the only classes are those represented by the pregens, and 3 ancestries (humana and elf are represented in the pregens, dwarf is available only when making custom characters.)
Of course, you can use full rules to create fully custom characters (I had a player make a kobold!), but it's not designed for that. xD
So yeah, a "player guide" different from the "hero's handbook" from the box is very unlikely, as it pretty much plays that role already, with a very limited selection of options that both adventures operate with the expectation that they are the only ones available to the players.

Bruh I just want foundry support, please.

Here to be another voice asking for a Foundry implementation. I want everything foundrified! But for now I want this product specifically foundrified.

While not quite as good as the official modules, this is one of the modules that can be imported with PDF To Foundry (you'll want a V11 install of Foundry to import it for now), and Narchy (the same mapmaker that does the remakes for the official modules) did do maps for this adventure that you can find on his drive
