of the things you rarely get to see, unless you're working in the games industry,
are design documents for commercial games.
Of course, people publish design documents templates and
write books and
articles about game design.
Al Lowe, who designed and development
some of the best adventure games ever made (Leisure
Pharkas, …), has posted a series of game
design documents for several of the adventure games he worked on at Sierra.
It's pretty cool to go over these documents and compare them with the actual shipped
game, plus it gives some real good insight to game design…
