There are games that are "steam is learning about" (mostly some newer games).
Steamgifts can't see them.

Some games are Profile Features Limited (see picture for an example), they are not included in the list of your games, retrieved by Steam API, therefore Steamgifts can't detect them on your account.
The same goes for most DLCs and packages.

There's quite a few reasons for SG to not recognize ownership, let's see if I can catch them all:
- Profile Features Limited
- Games removed from Steam
- DLCs [And any package containing at least one DLC; SG only considers a package owned if you have 100% of it, so this is a derivative outcome of the fact that DLCs never report as owned.]
- Packages which are misconfigured to not properly send information on any contained base games out through the API, leading to an inability to confirm ownership of the contained content [as the package seems to not actually contain any content that you could own].
I seem to recall there was an issue with certain early [seperately purchasable] Expansion releases, as well, but Steam has long sinced moved to just using DLC as the format for both DLCs and Expansions, so even if those did have issues and still retain them, it shouldn't be likely for one to stumble across them. While I'm unsure if Spore: Galactic Adventures was one of the expansions to have such issues, it's a good example of the format I'm referring to.
I don't recall if weirdly configured games [ie, such as can come about following the release of a new version of the game which shares the same store page as the previous version] also have ownership reporting issues, though I do know they [under such configurations] report $0 value (as removed games also do).
Games which were released within the past 24 hours, or have not yet released [eg, as can occur with kickstarter keys or certain bundles (namely, greenlight bundles in the past)] also report $0 value, so they're also worth mentioning for consideration [as, again, I'm not sure whether that also extends to having ownership reporting issues].
Did I forget any? ^.^

Regional versions / dev mess-ups.
You may use key that properly activated game, and when you click on Links => Visit Store Page on your /all-games tab on Steam it will redirect you to proper game store page.
But key activated game with different appID than the one it redirect to. Which means that checking against appID of won game will result in inactivated win message, and that SG will not prevent you from winning this game again, if you actiavted it on your own. As you have different appID in your library.

This happens quite frequently. I have over 6,000 games and cannot remember every title. I rely on syncing with my Steam account to only show games I don't own and can therefor enter a giveaway. But sometimes A game I own still shows up in the giveaway list and I enter for it thinking I don't have it already. If I win, then the person has to do a reroll, which is a hassle. It didn't used to be this way? Why all of a sudden is SG having trouble with their syncs?
