What?

No one is right.

It's still in the beta stage. Although the key activates the full game eventually, the beta phase is still in progress.

You're both right. It is both the beta, and the full game, and because of that it does not in fact appear in the game library. I myself own Starvoid, and Starvoid beta, yet if you look at my own games list, it won't be there.

Support is right, as there are some games that do not appear in the games list.

ok tnks all
