I'm not necessarily a hoarder, but I do far too often bestow unnecessary meaning to random objects in games. Silent Hill 2's board with a nail in it. The very weapon that got me 97% of the kills in that game was something very special to me.

My first outfit in KoToR which I wore on special visits back to the Tatooine.

In Monster Hunter, I am a hoarder because that game lives and breathes combinations of items, so if/when I gain a brand new item, I have every other conceivable combineable item in my inventory to attempt to mix it with. A tedious effort given the mechanics of the storage box and on-person inventory. There're well over 300 items in that game. =(

On hoarding star power. I am 100% with you on that one. If I'm not feeling a song, I won't throw it. Ever. It just doesn't sound/feel right. But in other songs, I will purposely wait for drop-offs so that the crowd's clapping can be heard more clearly than anywhere else. (Can't you hear me knockin', anyone?)

I would say that I'm needlessly fearing missing opportunites than a mere hoarder of goods. Things have to be special in order to enjoy the full effect. Which is why I only ever play certain games after 11pm, and why I always order a slab of ribs and fries when Wrestlemania rolls around. Good times.
