While many are still splashing the ripples from the Twixt or Myers or whoever’s attempt to explain sociological emergence in a one-sided, four-colored narrative, Orion – one of the developers for Lord of the Rings Online – put up an excellent post discussing emergent gameplay on his blog. He discusses how all exploits start with emergent gameplay and uses the Mines of Moria instance, the Grand Stair as an example. It’s well worth a read.
