I cant remember ever not having a games console in the house (my parents used to play old Ataris and alike from time to time).
I gamed a lot as a kid, starting with the sorts of puzzle games that my mum enjoyed, then fairly standard games on the megadrive, playstation and alike when they came out.
I probably played some sort of game most days, but still enjoyed imagination-based play as a younger kid and sports as I grew older. Gaming was definitely also a significant feature a teenage socializing though.
I was always an extremely high achiever and, outside of general puzzle-solving skills, I was surprised how often things I learned in games came up in school. I remember being asked as a class if we knew the meaning of a certain word, and the teacher being shocked when I both defined the word and was able to provide its Ancient Greek etymology.
I'm now work in a profession that I never would have entertained had I not played a game that sparked my interest in the subject.
I still play games most nights with my DP, as a fun, shared activity, and play a few casual games online with my grandmother (who lives is another country).
I probably played more than a lot of mumsnet parents would be happy with, but gaming has always been a positive influence in my life.
Caveat that some games are undoubtedly more beneficial than others, and some can obviously be addictive in a way that some people struggle with.
