Probably helped me become skilled in various areas (on a basic, yet practical area) such as level design which probably influenced an eye for web design which has landed me a position on my university law society committee which should make me stand out from the crowd on a CV and get me a career!!
On the negative, I probably become too comfortable, and could have been doing things other than sitting on a computer. But then my PWA position taught me a lot about people in general and how to approach them etc, which would be useful for any management role.
