Hi, thanks for the game but the key is not for this one, it's for https://store.steampowered.com/app/108200/Ticket_to_Ride_Classic_Edition from 2012, and i already had that one so i couldn't activate it.

I would tell you that you can delete the giveaway but there are 4 copies, and i don't know if support will let you reroll since it's a different game and it might happen again if it didn't already happen with some of the other winners.
