so you see no future for gog.com? any particular reasons? i'm till now not sure, if i should too backup my gog.com games.

Well there are possibilities, although ugly ones, that you can be locked out from your account here.

Either deliberately by some fiendish plan where your arch nemesis got your gog password and posting a lot of child pornography here -with your stolen identity- or by any other weird circumstance you did or didn't deserve to get banned or losing your internet capabilties.

Steam can lock you out of games pretty quickly, EA's Origin had some scandals with that, but come on, it's EA what do you expect...
With gog you can take the responsibility in your own hands and start downloading all those installers whenever you like...

I like that responsibility and I gladly take it.

GOG should be around for awhile. I backup GOG games because its easy and why take a chance? The games are DRM free and the old games are small in size, so they dont take up very much External HD space. I dont backup the larger games like The Witcher 1 & 2. Basically anything over 5Gb, i do not bother making a backup. I make sure i play and beat all the large games first. There is a strategy to my backlog.....LOL. I dont bother backing up Steam games because if they go out of business, they may not release a crack for their client and you might not be able to play them. My strategy for Steam is the same, play all the large games first when im at home with a good internet connection. Save the small games for when i travel and have bad internet connection. Here is how i recently played my backlog:

1. Max Payne 3 = 27Gb
2. Batman Arkham City = 19Gb
3. Battlefield 3 = 18Gb
4. Battlefield 4 = 25Gb (got free 7 days trial, i will easily finish the single player game during this time)
5. RAGE = 17Gb
6. The Witcher 2 = 15Gb
8. Medieval 2 Total War Complete = 13Gb

So you see, i play the big games so i dont have to worry about wasting my External HD space. I save that for the older and much smaller size GOG games.

How's that for a haystack when searching for a game title?
As far as I know neither Windows' search, OS X's spotlight, nor Unix's grep can look for "text" represented as bitmapped images.

That blessed fellow probably has a photographic-memory, so once he took a screenshot he doesn't need to use the search option...

It imported about 2/3 of my games, not counting DLCs or betas etc.

What's the difference between "finished" and "completionated?"

If I can get all my games on there, this might be a cool thing. Still playing with it, but fun.

I just finished loading in all of the games that were missing, so if you run the import again, it should pick 'em up. It won't re-add the ones it already added or anything.

The idea for "finished" vs. "completionated" is that finished means you beat the main game / story / whatever, but there might be side quests, achievements, etc that you could do. And then completionated is for when you've done everything a game has to offer. I'm torn on whether or not I want to keep the two options or just have one for "finished" and simplify things a bit.

If you really have thousands of games, than naturally it's not really a big help, but if you have for instance a couple of hundreds you could take grid view in steam choose the lowest picture size and take screenshot. I got 10 pics meaning almost 420 games- it's pretty easy to spot your game in a matter of seconds since it's in alphabetical order and every game has a discernible thumbnail.
As far as "haystacks" of games go, I'd say Excel is your best friend :)

I keep an Excel file, one for each platform (PC, PS etc.) main list generated from the nice folks at Wikipedia:
Wikipedia -> Lists_of_video_games
Its not complete, but a good starting point. Then I have flags for hard copy, which digital distributor, indie website etc.
Currently I have 20 Excel files, thousands of backlog, RSI, and an increasing supply of HDDs for backup :o)

Very good and informative replies so far, thank you!

I want to add that I actually am not all bad with Excel but I do use the OpenOffice variant for some time now.

Oh and there is more I want to brag about:
In fact I asked the guys from humblebumblebee *bzzzzzzzzzz* about a spreadsheet export function of the library and they reply in a vaguely positive way.

Let's just see how many decades it takes before we can see such a feature there...

You could use a spread sheet or pen and paper. I only get drm free games and then I download them and back them up so I don't have to think about it.

Yes, I'm a game collector, but I only collect the games that I fully plan on playing someday. The exception would be on Steam games that come bundled -- some of those I activate simply because they have trading cards... which I sell to pay for some of my game collecting *^_^*

Let's see, my primary gaming sites are Big Fish, GOG, GamersGate, and Steam, but I also have games at Desura, GameHouse, and the freebies at Origin. I pretty much know what all of my games are except that I forget what I have at Desura a lot. I keep having issues with their game downloader/interface, so I don't use them as often as some of the other services.

As for keeping track of codes, I keep e-mailing myself updated lists of all of the games I have available and their codes. It's why if you look at my trading list, you will sometimes see "TAKEN" in front of some of the games -- because I'm too tired to update my e-mailed list, and I use that as a reminder to delete the code(s) when I DO update.

Did any of that make sense? I'm really wiped out today -- it's been a long couple of weeks.
