6-10 : Slightly addicted to online games.
11-15 : Addicted to online games.
16-20 : Way too addicted, play less please.
21-30 : Unbelievably addicted to online games, just play less, a lot less please.
31+ : No life, please don't spend your life in front of a computer game, a bright future awaits you.
