I am really looking forward to the day when I can play with my son. But he is only 2 so I know I have a while to wait. But my question to you parents out there is how long? At what age did your kid start playing? I'm not talking about when will my son be a serious competitor but when will he be able to get the basic concept of the game. I could even make builds for him to fly. I know every child is different so what your kid did won't be the same as my kid, but a general idea would be nice. Thanks
