I've posted before about how I had the most amazing time playing the board game
Pandemic Legacy.
Pandemic (2007) is one of the most famous cooperative board games, and it is a great game in its own right. But the idea of a Legacy game is to add elements to the game that change each time you play it.
Stickers are applied to cards, new boxes are opened revealing new pieces to play with, and new surprises are unveiled as an ongoing story unfolds over the course of a 12-24 games.
It is an incredible experience -- by far the best gaming experience I've hard in decades of playing board games.
It really makes me want to get into making one of these kinds of games..
Anyway, the designers of Pandemic Legacy recently gave a couple of talks on the development of the game, and the talks are surprisingly insightful and useful for anyone considering working on this kind of thing, and I hadn't realized how seriously they considered some of the issues that just seemed to flow naturally during the course of the games..
Highly recommended for anyone interested in this kind of thing..
