To be fair I'm not even sure what it is. I was recommended it for my 15 yo aspie son. He's finally joined. Not worried about him so much, but now my 7 yo wants to join. 
So my question.....is my 7 yo too young? Can't find any restrictions in age, but then I didn't look for long. A bit out of my league! Give me roller coaster tycoon any day.
