I just noticed how the game magically inflated as well. Is this remade in new engine, or just larger uncompressed textures? Saints Row was three times larger as well.
Did many Bothan spies have to die to bring you that information? Seriously, where did you find that?
If you only have the Origin version I don't think you can upgrade. As the game isn't owned by EA anymore. Though you may be able to get EA to get you a steam key.
