Its Happening Now Fuc!ing Amazing

Downloaded also. Do you see anything unusual with your download though? I had 2 download files of less than 1gb each, then the main game downloaded without showing in notifications- had to go in System Storage Management to see what was happening. I downloaded plenty of games before, but not a preorder like this, is this normal? Also, the file size is about 20gb- does anyone else think that's a bit small for a full game ie more files to come? All very strange, got me on edge, especially considering how poorly communicated access to the beta was. Is this just how bungie work, or is it all preorders? Got a bad feeling about this drop...
