Doesn't change the fact that you were wrong. don't bend it like that. Take it like a man.
In game purchases are more common than exception these days, so no. You're not getting away with this one.
Wrong how? Theres nothing that is "free" as you know as well. When the whole game economy is to make people pay for stuff in games (well it's for kids in the first place), it's not a "free game". Well, I might be wrong about the "ad thing" though.
