since it's the Beta, I'm guessing that's is based on the total hard drive needed for the installation:zipped file, un-zipped copy and transfer for the proper folder. Much like with Steam, you need about 24 GB to download and install a game with just about 8 GB. Too much even with that imp. it's a god damn Beta :p
