I'm 14 years old. My birthday is February 6, so I will be 15 soon. So, I guess I can go to Australia and be the recommended playing age.

lol.
Anyways, the population of halo is getting younger and younger. 90% of the people I play with are 10-15 years old. However, my dad plays and he has someone that plays almost all day everyday and he's 56.
(For anyone who knows pros, how old is Pistola? 11? 12? lol)
