I know not everyone here has OCD like I do (I have it only very mildly) but when it comes to gaming certain things really make me go "Oh god, I have to do that" or else... I have no idea.
For me, in games that have droppable items like Xenoblade or Zelda I always get the item even if I don't need it. Let's say I'm playing Zelda and I have full hearts or my wallet is maxed out but then I attack an enemy that drops a rupee or a heart -I'll take it even if it won't add to my already out maxed out health or money.
What about you guys? Or am I just weird? XD
