Eh, I think the game's appropriate for different kids. There are some 13-year-olds who have been through worse stuff than people twice their age. Even if they haven't had a hard life, maturity does NOT come with age. It could be that I allow my first daughter to play TWD at 12, and my other at 15. It all depends on the person, in my opinion. :P
But I do agree - I've been surprised. I thought that we were all my age or older. Not that I expect youngins to be immature or rude, but the kids on these boards do seem to be truly insightful.
And StrongBrush1, I love you! lol! I have been so curious about seeing ages side-by-side, but I'm rather lazy when it comes to those sorts of things! I really appreciate the chart! x3
