What an emotive subject. We all like to think we are giving our kids good tools to become nice, helpful and confident members of society.
Jane McGonigal - Reality is Broken : Why Games Make Us Better And How They Can Change the World. A very influential book on gaming written by one of the top 10 most influential women of 2010. She argues that games are bringing a sense of community back - according to DH (bottomless pit on this subject!!).
Although I don't like them, I sometimes watch my DS's (9,6 and 5) making 'worlds' on Little Big Planet and it involves a huge amount of imagination and concentration - and working together as a team. Much of their enthusiasm is fuelled by DH and it helps that he has a real interest in it and will sit and explain who made it, why they made it, etc etc....
The gaming industry is now bigger than the music and film industry. There are many very good jobs there for talented individuals. Technology is changing so fast, we think that our DS's having a good understanding of this is a huge benefit to them, along with reading, writing, sports and all the other wonderful things out there that they have access to.
For us, but only because my husband is in the industry, there is a much bigger picture here - I for one will be very interested to see what our children's children will be doing with their free time.
Hope that doesn't come across as 'smug'.
