sometimes I get sick of looking at all the video games on my shelves. i don't play every one, and it's a huge taker of space. it's to the point where i basically need an entire room dedicated to putting my games in, and sometimes i think selling them all off would be way easier.
the worst thing about big collectors is they are adverse to selling, so many times they will die and their family just winds up getting rid of all the things they spent so much time collecting. the trick is getting past that feeling of attachment and eventually sell your collection off so you can enjoy the fruits, instead of having it sold cheaply or thrown away when you die.
I don't collect games per se, but I just never get rid of them; consequently, I have every game and system I've ever owned (with the exception of a few games that have been lost or taken by my brother) since the NES. On the one hand, I know that I'll never play most of them again, but, on the other hand, I've had some of them for thirty years, so I *can't* get rid of them now. They take up a fair bit of space.
One thing that has been bothering me recently is that both my Xbox 360s are toast (one still functions slightly for media, but overheats when playing games. The other won't even turn on), so all those games are effectively paperweights at this point.
I can't think of something I collect just to have that I don't like though.
