World of Warcraft: one simple line of code can cost you dearly

Procedural Dungeon Generation: Cellular Automata
Last time we looked at generating random dungeons for video games using the Drunkard’s Walk algorithm. The Drunkard’s Walk is fun to play with, and often generates cool levels, but it’s also pretty unreliable.

So You Want to Be a Hero?
Rule #1 is “The Player Must have Fun.” It’s trivially easy for a game designer to “defeat” players. We have all the tools and all the power. The trick is to play on the same side as the players, to tell the story together, and to make them the stars.

The Road to Ultima V
It’s not easy having a software superstar for a little brother. That’s something that Robert Garriott, president of Origin Systems , had more and more cause to realize as the 1980s wore on.
