World centric or player centric?

“How many times will a developer promise me that my decisions will impact the world before I actually see it?”

... when the world itself is designed to be the game, with player participation a secondary consideration.

What I mean by this is first design a world, populated with whatever is in that world, and design it such that those things are determined by the other things in the world. Make the world a dynamic model, even absent of players. Design and develop the world such that, even if no players ever logged in, the fates and fortunes of the world inhabitants will ebb and flow.

Now, add players. (Then fix all the bits that get broken by adding players).

Contrast this with what you've likely seen a few times now: design a world as a static landscape, add players, and then add mechanisms for players to affect that world. The design of such a world is entirely player centric - without players exploring their personal destinies (aka "consuming content") the world effectively ceases to exist.

Kill 10 rats ... or kill 4 specific rats

Which type of quest would you prefer to do:

• kill 10 rats, in a nearby farmyard with lots of rats
• kill a red rat from the barn, kill a black rat in the forest, kill a white rat in the house, kill a brown rat in the yard

Certainly, the first quest could be more efficiently completed, but the latter has more potential for a varied experience.

Fine print: they both would take about 5 minutes to complete, both reward 55 silver and 1,250 xp (from mob kills and quest completion).
