Registering a game here is effectively permanent. The game registration process is something of a kludge in the forum software and Paradox have no ability to:
- de-register a game
- extract a game key from the forum registration
- move a registration to another forum ID
- merge forum IDs. Remember that having more than one ID here is against forum rules; if you forget your login details here, please submit a ticket to paradox.zendesk.com with as much detail as you can.
Second-hand games: as mentioned above Paradox have no way to transfer a game's registration to another ID here, so if you buy a game that the vendor has already registered here, there is no way to remedy that. Replacement keys will only be considered for new game purchases.
