So if you did a 60 hour working week, and someone else did the same job and did a 20 hour working week, you'd be happy to pick up the same wage packet? Surely your going to feel either they are getting overpaid or your getting short changed, whether your the same gender or not.
Anyway, I know this is probably controversial, but not only do the men play more games, I dare say they attract more interest. A lot of people won't have given a toss about todays game but people will be making plans to make sure they see tomorrows.
