Question about fielplanet 7 day trial

[Adun]

They say you'll have to buy the game afterwards for a new code, but arent there other ways to get the code?

What if you buy one of the 3 month game cards with a code on them? would they work or do you HAVE to buy a code from the box?

BTW, can anyone guess what the words in my sig mean? My german isnt perfect, but i have a decent idea of what it means. This is from the tv show FamilyGuy. Hitler had his own talk show and he yelled this out. (dont worry, its not something really bad, a least im pretty sure its not)

You need the CD-key on the case to activate the account. The game cards are just an alternate way of paying, the code on them just proof you actually bought one.

The CDKey has nothing to do with payment, its just proof you have a valid copy.
