So I am gearing up to clean up my digital game collections installation files and looking at the list of all the game folders I struck something. I have gained many duplicate games over time.
As I always download to back up my games for later installation, I just download every game at time of purchase. This obviously leads to duplication of some games, especially from bundles.

So I am looking at the games I have over several providers and considering which copies are going to be binned.
I have games with GOG, HubbleBubble(SteamTrubble), GamersGate, Indie Royale, Indie Game Stand, Groupees and maybe one or two other bundles and CD too.
All of my backed up games are DRM-free as Steam is only a placeholder until the developers release a game DRM-free, at which time said Steam game is removed for the DRM-free copy.

So I am now cutting back games down to suppliers to keep only a single installer.
So I am going with the most left supplier of a game being kept with all additional extras moved over. All else is then deleted for space.
GOG <-- HumbleStore <-- GamersGate <-- Indie Game Stand <-- Indie Royale <-- Groupees <-- HumbleBundle <-- Other <-- CD.

Now my unorganized explanation is over. I was just wondering if anyone else has done this, or am I alone with this behavior?
I archive installers that have produced an installation I've played significantly. They are valuable because I've verified they work on my system and any save files produced are compatible with them.

For unplayed installers, I have no firm preference. I'd probably choose the best maintained one.

Well most games from Indie Royale and other bundles often have Desura keys for their games (and standalone installers) minus Steam, and minus a few that aren't on Desura.
So for me its a GOG map, a Desura map and a seperate map for any games from the bundle that aren't on Desura.
Trying to get rid of my cds as they just take up space.

For me it's:

CD<--GOG<--Groupees<--Humble Bundle<--Steam<--Anything else.

CD is for collection purposes, GOG is for the support/compatibility, everything else is for the cheap prices.
The GamersGate installers won't work unless you are online for the verification check, unless you save the dumped files from the installer before installation starts. I'd put GG after Humble Bundle in your sequence unless you normally save the dumps. My assumption is that you're keeping your games safe so you can play them even after a nuclear holocaust :)
GOG <-Groupees<---------------Humble
I usually keep the GOG ones over the others with the extras in the same folder. If a game came with a full OST in a bundle that wasn't in my GOG version I'll download it and throw it in the folder also. The rest I don't really care which version it is as long as the game works. Gamersgate ones though I tend to back up right away so I won't have to fool with their downloader if I need the game again.

Any games I have on CD I keep images of even if I have digital bought versions.

I usually keep all installers unless I'm certain that one is inferior (e.g., outdated, or has DRM while otherwise being identical). If installers from several sources are exactly the same file, then I keep only one copy, but put a note in the respective folder that I bought identical copies from their respective sources.

With games in my archive that take up 20 GB each, it really doesn't make sense to force deleting a 200k installer unless you're sure it's a duplicate or inferior.
If it's DRM-free then the only other concern is how up to date it is. For that reason I'd place the GOG version above all others as GOG seem to be far better than everyone else when it comes to providing patches for DRM-free games.
I keep eeeverything.

On that note, I'm looking (and saving up) for a new storage solution.
