Statistically that's true, huh? Do you have a source to back-up that info?
How about personal experience?
Four years of dealing with little kiddies on Halo, Cod and Gears of war. The vast majority are pre-teens swearing because their parents don't care. It's pathetic.
Ps not to bash those that joined in June seeings as I only joined a week prior but I don't think people that just joined should have been let in the beta, for a couple reasons.
1. They joined because they saw 'free'
2. The accounts will most likely go inactive
3. And (not sure) the ability to make multipule accounts and sign up.
