Zairii

I just saw Sacred 2 on the shelves at the local shop and after reading I saw there was PC version and multiple versions- what is the difference? Should I get the Australian version of the Gold Edition from somewhere online (no stores here have it) or can I download the version from this site (I read that the money goes to the site and sacred wiki which I've spent some time reading so it would be good to do that). On a side note- I read on the wiki that the Inquisitor can't use swords but I've seen screenshots where he appears to be duel-wielding what appear to be red-lightsabers are they not counted as swords? If not what are they?
