Well, I have started to go through my 25+ years of collecting physical copy games. The idea being to remove all duplicates across platforms, drop those where I have a digital copy, basically just major downsize it. Currently this is 80 360 games, 40 ps3, 300 pc games (dvd, cds, boxed), and counting. Its hard though, to let go of these, especially the boxed ones, but they do take up a room on their own. Anyone else done this, any tricks to numb the pain?

Sell them on ebay, buy more games for the money you earn

eBay, I guess, but you could also see if a local game / media store takes trades. Get less, but also less hassle than dealing with a bunch of individual eBay shipments.

Does UK have craigslist or something like it?

Good grief, at first I read that as more than eighty thousand games! O_o

Start a big physical giveaway!
You will feel better knowing that some fellow GOGlodytes will be able to discover some games you liked thanks to you ;)

You could dedicate a room, or a few shelves, to a collection like some people do (rather than getting rid of them).

As others have suggested, make sure the games end up with people who will appreciate them. Heck, just recently I had a very similar problem with all the stuff left behind by my grandmother who died last year. There were tons of things I couldn't get myself to throw away, luckily I ended up giving it away to people who appreciate it, ultimately even feeling really good about it.

+1 to eBay'ing them. Before you do so, scan the maps and manuals and any other bonus materials the individual games might have, make ISO images of their soundtrack CDs and other bonus goodies and if the game(s) are on GOG and do not have such goodies, or if your copies are better, contact GOG folk like JudasIscariot to see if they want copies of the stuff they do not have already. GOG can talk to the publishers to secure the legal copyright situation and then obtain them from you perhaps and add the missing bits to the catalogue for everyone. They've done this with a number of goodies in the past, but they're damn hard to come by sometimes. :) Once that's done, sell them on eBay.

Oh, and let us know all the goodies you have first so we can help out nagging the right people if need be. :)

See if you can get NES interested. That way we can find out where he lives and take turns throwing flaming bags of dog shit on his porch.

Yes, ebay seems likely. Craigslist, isn't that some hook up network or something? Not quite that many, but lots, lots and lots. I have a room dedicated already, its full. The other room is full of books and other stuff. Got nowhere to put things, so I am downsizing. Yes, I think the pc games and boxed ones would only goto a collector, can't see anyone else wanting them. I would need a couple of secretary's to do everything. Already spend hours collating lists of whats there, getting patches, mods and yes, iso'ing any soundtracks and that. Its only the boxed ones which have nice extras, will see what jumps out at me.

As an example, I have 6 copies of BG2, one big box, two dvd, one collection, one small box and one booklet. Not to mention the GOG version. This is when you realise you have a problem :O)

I'm willing to buy if your willing to ship! Interested in the 360 games and PC games! How about consoles?

Understandable. :) That does leave you another option though, which would be to make a big list of everything you have and send just that to GOG to see if they are interested in buying some/all of it off you in one shot. :) Surely JudasIscariot is reading this and short circuiting his keyboard with drool as he reads. :)

:(

If relevant, do what I did: get your wife to do it for you.

Maybe it's just the ratpack in me, but I'd urge you to reconsider before getting rid of them. No place in basement, attic, garage? Just pile it in a box and put it under your bed. Give it to your friend/sibling/parent to keep for a bit? If only temporarily.

Think about it: once it's gone, it's gone. You wouldn't want to regret that you haven't kept them if some time later you move to a larger place.
