The other day, I bought the original SoF used at a thrift shop. Well, my CD key was able to get me to the singleplayer portion but refused to let me play multiplayer because the key was already used for multiplayer by the previous owner. I haven't run into a lot of games that do this, but I was wondering if SoF 2 is the same way. If I buy SoF used (because new is ridiculously overpriced at this point), will I be able to play the multiplayer even if the previous owner used it for multiplayer a long time ago?
If I remember right, all the SOF2 versions that are out in shops now have for some reason the same cd-key.. That also means that key is banned cus someone hacked on that cd-key, which also means that's the reason why you can't play the multiplayer version. Perhaps you should try to get another cd key from a key generator or ask a friend's cd key.
