I think it continously ingrains a certain type of "testing the waters" process:

1) Find an operation you can perform 2) Is it likely to cause permanent damage? If yes, goto 1. 3) Perform that operation a few times 4) See how it combines with the other operations you have already mastered 5) Repeat

I don't think it's something inherent to video games as a medium, it's just the most common activity that requires you to learn a new interface every few weeks if not more often. Professional tools of any kind will strive to retain a familiar feeling, and everyday tools like household appliances, cars, or cellphones don't get replaced nearly as fast.

(Sorry, bit of a tangent there)

It's OK, this is rapidly turning into LW's General Videogame Thread anyway.
