All of the links you have provided point to re
-sellers. Of course they will try to re-sell you the keys or the phisical copies they have left in stock! It doesn't cost them anything, yet the game isn't sold by the official sellers
AND it was discontinued by its Publisher (EA).
So yeah, technically you can still purchase a Key or phisical copy ... but A) it's not worth the price at all because B) that license key you are buying was valid 3 years ago or so (when Battlefield 2 was still supported by its publisher), nowadays it just a string of numbers and letters, with no actual value. :'D
@Liana if you cannot join our services again by next week, please send me private messages either here or on our Discord Server and I can see if we can come up with something.
@John believe me, although I admit I don't recall which installer I shared with you, there was a key manager
for sure. I also recall that you may have stated you have your key safely stored with your phisical copy of the original game or something along these lines?
