Let's look at the typical life-cycle of a collectible using baseball cards.
When they first came out in the early 1900s, nobody really cared about them. Through the 70s and 80, they were mostly seen as kids stuff and abused, lost & thrown away. Supplies of cards up through this time are fairly limited. Around 1990, news hit of a baseball card selling for half a million dollars. Things changed overnight - every kid was treating their cards like treasure. People have held on to them in pristine condition. These days, you can buy unopened, complete sets of cards from the mid-90s for less than their original retail value. They have become so un-collectible that their value hasn't even kept up with inflation.
Video game collecting has passed this point. Sure, you might still see big deals on used NES collections but anything much newer was sold in large enough numbers and preserved well enough that unless you have sealed boxes, it's just used junk. There's always going to be exceptions but, for the most part, I wouldn't plan my retirement on keeping my XBox clean.
