You have heard of sentence structure, no? I fit in the 14-17 age range, and I'll tell you that I don't know one other person in my school that has any CM game. Regardless, I'm pretty sure BFC doesn'y gear a release towards a 4 year age window, but produces games for whomever wants to play them. Doesn't matter if you're 15 or 83, if you find the subject matter interesting, and you like the game play, then they designed the game for you.
