FC2 isnt worth to buy an original
get originals of those which has gr8 online capability.
And whete is the 3.7GB specified?
Ubisoft site or ny illegal/warez site?
normally torrent/warez ones will be highly compressed for easy download. They use high compressions like UHARC or the likes. So after extracting the contents it migh probably be double or more of its original size.
and the developer is assuming we are installing in C:\ partition and they estimate the recommended free space taking into account
*space for installation
*swaps
*temps
*saves and profiles
*and some miscellaneous
so it might be 12Gb in this case:-P
