Faction Auction - the mechanism?

Post by BossPi »

Can someone explain how does an auction work behind?
What happens after every player enters how much VPs they are willing to pay?
Since I didn't get any clue when reading though the game log.
Does this auction mechanism have a name that I can google and learn?

The auction specifics are detailed in the How to Play section.

After you read the How To Play and the log, if you have specific question we'd be happy to answer them. Usually, we find that people's questions are all answered between a close reading of those two sources.

The "How to Play" section is at the bottom of every game you play online. You can also find it here:
https://en.doc.boardgamearena.com/Gamehelpgaiaproject

And the log refers to the game list -- the list of events -- for a particular game. Every game you play on BGA has a log. Read the entries for a Gaia Project game and it spells out specifically what's happening at every step of the bidding process.

Hi, I read the section several times but I don't get it.

Especially this part I don't understand: "...each player automatically bids on the faction with the greatest difference between the faction's current bid and that player's maximum possible bid."



Lets assume the following bidding situation:

Player / Faction 1 /Faction 2 / Faction 3
Player1 0 6 6
Player2 2 5 0
Player3 0 3 6

Is this how the round-robin is resoluted? (I guess no but I have no better idea)

Player / Faction / Bid
Player1 2(?) 0
Player2 2 1
Player3 3 0
Player1 3 1
Player2 (2) (1)
Player3 3 2
Player1 2 2
Player2 2 3
Player3 (3) (2)
Player1 3 3
Player2 1(?) 0
Player3 3 4
Player1 2 4
Player2 (1) 0
Player3 (3) (4)
Player1 (2) (4)
Player2 (1) (0)
Player3 (3) (4)

Result:
Player1 gets faction 2 for 4 VP
Player2 gets Faction 1 for 0 VP
Player3 gets faction 3 for 4 VP

???

Thanks for helping

That looks right to me. I can't remember what happens if there's a tie (where you posted question marks), but I vaguely recall it's broken by whether someone else has voted on one and not the other, then broken randomly after that.

Anyway, it appears you've got it. If you have ideas on better wording to clarify how it works, just edit the wiki and share your improvements.

Edit: In the case of a tie of [maxBid - currentBid] on multiple factions, ties are first broken by the one you had the highest maxBid on (meaning you wanted that faction the most) then, if still tied, chosen randomly.

So, I also had some questions as to the way it worked and also thought that it would be awesome to be able to use that logic to speed things up when playing live. And I agree with you, I had a hard time understanding the text in the how to play section. What helped me understand was to think that each player would bid for the faction that was the best for the current bidding situation or, in the words of the BGA devs, the biggest difference between their maximum bid and the current faction bids.

Here's a log that I managed to generate from what I coded for myself:

Code: Select all

John is willing to bid up to 15 for the Firaks.
John is willing to bid up to 5 for the Taklons.
John is willing to bid up to 7 for the Ivits.
John is willing to bid up to 19 for the Terrans.
Phillip is willing to bid up to 11 for the Firaks.
Phillip is willing to bid up to 27 for the Taklons.
Phillip is willing to bid up to 9 for the Ivits.
Phillip is willing to bid up to 4 for the Terrans.
Paul is willing to bid up to 25 for the Firaks.
Paul is willing to bid up to 18 for the Taklons.
Paul is willing to bid up to 20 for the Ivits.
Paul is willing to bid up to 27 for the Terrans.
Sasha is willing to bid up to 30 for the Firaks.
Sasha is willing to bid up to 13 for the Taklons.
Sasha is willing to bid up to 15 for the Ivits.
Sasha is willing to bid up to 13 for the Terrans.

John increases the bid for the Terrans to 0.
Phillip increases the bid for the Taklons to 0.
Paul increases the bid for the Terrans to 1.
Sasha increases the bid for the Firaks to 0.
John increases the bid for the Terrans to 2.
Paul increases the bid for the Firaks to 1.
Sasha increases the bid for the Firaks to 2.
Paul increases the bid for the Terrans to 3.
John increases the bid for the Terrans to 4.
Paul increases the bid for the Firaks to 3.
Sasha increases the bid for the Firaks to 4.
Paul increases the bid for the Terrans to 5.
John increases the bid for the Terrans to 6.
Paul increases the bid for the Firaks to 5.
Sasha increases the bid for the Firaks to 6.
Paul increases the bid for the Ivits to 0.

John will play the Terrans(4) starting with 10 points.
Phillip will play the Taklons(2) starting with 16 points.
Paul will play the Ivits(3) starting with 16 points.
Sasha will play the Firaks(1) starting with 10 points.
