1. My passion for games
2.My 1st collector's edition was Starcraft 2 and then WoW:Cataclysm CE but i started collecting some months ago With Batman AC CE and now i have 20 Collector's Edition and many other stuff(figures posters, etc etc.)
3. Well i don't have many extremely rare things in my collection but I love my AC2 Black Edition
PS: I only buy things i like about games i like and not just because something is rare.
PS2 I don't keep anything sealed
I prefer owning something i enjoy than owning a box that costs more ( to be honest sometimes i think if i should open it or keep it sealed but then.. i open it and i forget about it lol)
