How the F do so much people have so many games to gift and trade ??? (possible answer in my post ?)

Hi,

DISCLAIMER:

I AM NOT ADVERTISING. I found the below link in an article about Terraria clones on a famous website called Squido (or Squidoo I don't remember).

I am amazed by the number of stuff people have to trade or gift. Some have like 10 or 20 or even more games ! Are you guys all billionaires or is there a trick that everyone knows and I don't lol ?

Are websites where you fill in surveys and stuff for points a solution ?

I hope someone can shed some light on that !
