Well if I were you I would buy it here.
1. Being because if you bought it here and you had a problem (involving the game from here; Im not sure if you buy it from a different company it will have a bug that no one could fix
?)they would be able to fix it-the forumers-.
2. You dont actually know who is pirating the game. Well... you usually do, but just be careful with it
PS. This is kinda off topic. I just had a lightbulb moment for it lol.
