hello, this should be a valid key. ive had this key for years.
afaik it's redeemable in NA steam.

if it's not valid and cannot be redeemed, drop a comment, and i will see what i can do.
please double check to see if you have this game and it can be redeemed in your country before you enter.

in the case that a key cannot be redeemed, i may request a deletion.
