You are right, even though they are video games you can always learn something from them and apply it in real life, when I was a little younger, I was somewhat addicted to online games but things change when you have responsibilities and priorities.
I liked the first photo you used, "MU" was my first mmorpg :) I do not know if you used that photo to quote the scammers haha, but I remember that in the server where I played some people sold the game currency for money real, and the scams were present.
Dude MU was my first MMORPG as well! I miss those days. Twisting slash and evil spirit..
