-You can play with a board games database from boardgamegeek.com.
-
-## Download the Database
-
-```sh
-mkdir board_games
-cd board_games
-curl -Lo bg.zip 'https://www.kaggle.com/api/v1/datasets/download/threnjen/board-games-database-from-boardgamegeek'
-unzip bg.zip
-```
-
-The header line shows fields with a bunch of colons, which will confused `recutils`, so we'll have to get rid of them.
-
-```sh
-sed -i '1s/://g' *.csv 
-```
-
-Convert the games to `.rec` format.
-
-```sh
-csv2rec games.csv > games.rec
-```
-
-## Queries
-
-If you try to look at older games, you'll find lots of results.
-
-```sh
-recsel games.rec -e "YearPublished < 1800" -c
-recsel games.rec -e "YearPublished < 1800" -Cp Name
-```
-But most are wrong.
-The problem is games with a `YearPublished` date of `0`, probably because the year published is unknown.
-
-```sh
-recsel games.rec -e "Name = 'The Goblin King is Angry'" -p YearPublished
-```
-
-Fix the query by removing games published in '0 AD'.
-
-```sh
-recsel games.rec -e "YearPublished < 1800 && YearPublished != 0" -R YearPublished,Name
-```
-
-Or fix the database setting `YearPublished` to 'unknown':
-
-```sh
-recsel games.rec -e "YearPublished = 0" -Cp Name
-recset games.rec -e "YearPublished = 0" -f "YearPublished" -S 'unknown'
-```
-
-Strategic games which work best with 3 players, sorted by Average Rating:
-
-```sh
-recsel games.rec -e "BestPlayers = 3 && CatStrategy = 1" -CR Name --sort=AvgRating
-```
