We’ve added (and are continuing to refine) a major new feature on CouncilRoom.com: Popular Buys.
By default, it provides static stats about Isotropic’s population as a whole; you can see, for instance, that Fishing Village is the most popular* card in the game — even more so than Province or Colony! In fact, Caravan and Nobles are both also more popular than any Victory or Treasure card. At the same time, poor Chancellor wins the prize as the least popular card in the game. Even Coppers and Curses are bought more often than Chancellor.
*To be precise, this ‘popularity’ is defined as the percentage of decks in which at least one copy of that card was gained. Technically, this is the number of players who bought or gained at least one Fishing Village in a given game divided by sum of the sizes of games where Fishing Village was available.
This “popularity” data is especially interesting when compared to “Buys”, which is a rough average of how many of each card each player buys. Unsurprisingly, non-terminals and Victory cards top the list; the highest terminals are Goons, King’s Court, and Bridge, which makes sense, since they all thrive when combined with each other.
In addition, “win rate given buy” provides a rough proxy of a card’s strength. Naturally, expensive cards tend to top the list, but so do many of the $5 attacks, as well as several Alchemy cards. Interestingly, Copper and Curse also do well, since if you’re buying them, you usually have a pretty good reason.
Most exciting, however, is the per-player data on that page. You can combine frequency of purchase, win rate given purchase, and win rate given availability to identify individual strengths and weaknesses; for instance, theory buys Lighthouse and Conspirator fairly often, but does quite poorly with them. rrenaud‘s long and futile fascination with Talisman reflects on his page; Obi Wan Bonogi, the top player on the leaderboard, shows a similar weakness for Quarry. Both, however, excel in sets with Vineyard, probably indicative of a love of Action-oriented games.
We hope you find all this data useful (and possibly educational)! If you have any suggestions, please let us know either in the comments or on the CouncilRoom uservoice page.
