Tried it for 3 months with my kids as an experiment. I think they got too caught up in how to beat the game, and how dumb their AI teammates were, and maybe didn't draw parallels to hockey enough as a result. So perhaps they were too young, but then again 12ish is about when you need to get this stuff. IMHO if your kid is motivated enough to spend 10+ minutes extra a day on hockey at home, there are plenty of things they could do for free that would help them improve (for example stickhandling with their head up so they can make those awesome plays that Intelligym supposedly teaches).
