Pretty much what Midland said ^.
I buy CEs for games that me and my boyfriend would have bought anyway (even without a CE) as we will open them and play and enjoy the games, and put the contents on display
There have been a few (okay, probably a lot of!) instances where I have bought a CE where I had no interest in the actual game, purely because the CE looks nice/has awesome contents/was a really good price/etc.
Sometimes I think to myself "holy shit" because it is a LOT of money I spend each month on CEs, but I enjoy hunting them down and having them on display for all to see, so it doesn't bother me too much.
And I'm too much of a hoarder to ever be able to sell any of my CEs, so I could never do that! I'd regret it instantly. I love my CEs too much

I'm so sad!
