In that case, for sake of comprehensiveness, let me also note that DLCs, packages including at least one DLC, and games removed from Steam will all also not properly show ownership. I recall that there are a few rare instances of games being misconfigured [usually because of a different version of the game releasing] in a manner which'll also cause the issue, and perhaps a few other obscure causes, but those aren't really things you can plan for.

So the main thing when creating [or entering] giveaways is just to keep note of whether a game is Profile Features Limited, DLC-based, or removed from Steam. ^.^

In any case, this game was bundled over a year ago, so I'm surprised there hasn't even been a single review for it yet. o.O;
Doesn't seem as though it'll be leaving Profile Features Limited any time soon, in any case..
