Explanatory Notes

1. The table is a study of game design innovation by highlighting the first introductions of each game mechanism, along with the games in which they first appeared.
2. Each "element" box displays, top to bottom, the year in which the game first appeared, an element code, game title and the mechanism that the game introduced.
3. Access further information about a game by hovering over its element code.
4. As the pace of game invention accelerates, elements are arranged in three series, first by centuries, then by decades, finally by individual years, the gaps representing areas without apparent innovation.
