As some of you might be able to tell I got the thread title from the game Borderlands 2. And in that I am a pretty solid completionist. I also try and collect every SMG in the game (looking for better and better) which I understand is an impossibility as there is a bazillion different ones.
I also have two characters I am trying to open all boxes/containers with. And generally try to get all challenges.
In BO2 I try to hack all of the equipment on the map to see how many people I can kill with their own equipment.
I also fancy myself a collector and I have through the years gathered quit the collection of things I deemed collectable (redundancy FTW). I am also a completionist which means that when I collect something I have to have everything about the specific item/thing that I am interested in.
I have a thing for locks. I like old locks. Strange locks, weird and old locks, locks that require puzzle solving to open or weird shaped keys sometimes more than one. So I am always on the look out for these items.
I have other collections but the above was probably one of my first or the oldest goes at collecting. I have even started others collecting things, I started my brother collecting cuff links but with as much as he is gone for work I usually end up getting stuff for his collection.
I also bought a Kindle Paperwhite and am steadily collecting all the Warhammer 40k books as they come out in ebook format.
I used to paint little lead figures like the forgotten realms type which got me into reading R.A. Salvatore which in turn made me fall in love with the Dark Elf series of books and so now I also collect anything and everything surrounding Drizzt Do'Urden and the world he lives in.
So what do you guys collect or feel that you have become a completionist about?
