Quoted from smokedog:12 and 14. They play like 2 games a month. Below avg players at best, and they can complete modes.
It's the same with my two boys, aged 9 and 12 but they play most afternoons after school.
We have spent hours and hours on a few different occasions playing the pro on site with the view to buying one.
I really like that it is hard and have no hesitation in buying one as I really enjoy the game but I wanted my kids to make the final call as we play games together and it's important that they have a say. No point buying something they will get the shits with in 2 weeks.
I kept waiting for them to say it's too hard we want to get something else but every time without fail the feedback is yeah it's hard but we love it and can't stop playing it, can we get one.
