At any game's page, I can't add a game to other stacks.
Exemple: I've played Duke Nukem, I have finished it, BUT I don't have Duke Nukem (cuz I borrowed from a friend)... So I can add only in "Want to play", "I'm playing" and "Finished" stacks.
I want to add the game at any stack what I want... I can play A game without finishing it, right?
