Pastimes and paradigms : games we play

Recently, I came around this nice website:

Pastimes and Paradigms: games we play

which is an excellent online exhibition on the history of games from 1800 onwards. Published by Cornell University Library's Rare & Manuscript Collections, the brilliantly designed site considers a wide variety of antique and modern games. The chapters have amusing alliterative titles, and feature images of games, rulebooks, and strategies, looking at games from around the world, television tie-ins, and famous ones such as monopoly and chess. The social and cultural importance of games is explored, and the exhibition highlights how games are primary source material. (Some of the features on the site require Flash and Adobe Acrobat)

What are the games, you remember having played personally?

And why, do you think, many of these games disappeared?
