Luckily I had it already added to my account, but what about multi-player? Because I can only login once in Origin with one account?! Well, luckily I found a solution.
On many request including mine :P I present the Origin version of Battlefield 1942!! This game was until may last your for quite a while a free to play game, but now gone in the database! I was so disappointed because I finally have this working as I wanted and now the game is gone.
