Am I the only 1 who keeps his games for collection purposes

[Kresnik]

Nope. I have a full compliment of PS1/2/3 + GC & Wii games.

My issue with used games + collecting is twofold.

Just as I've got a big collections of games, there are many more games that I've bought; liked, but not enough to think "I want to keep this game" and then sold/traded in. Happens sometimes when I buy later versions of games. Like, I bought Sims 3/Sims 3 Pets for PS3 but decided that if I ever get an itch for console Sims in the future, I won't need both games, so I traded Pets in.

If I'm limited to how I can deal with these games once I've decided I don't want them, then it's an issue.

The second problem I have is that I still buy a lot of old pre-owned games. I mean, I still buy PS1 games from time to time. Most recently, Colony Wars. Applying this logic, if I'm still gaming far into the future and it turns out I still want some PS4 games which are no longer in print and then can't be bought pre-owned, then again it would be an issue for me.

But to stay mostly on topic: no. I hoard games. Not so much for collection purposes, though, but because I often come back to them time-and-time again to replay.
