Downloaded it this morning, just waiting to get pesky work, family, eating, etc out of the way with.
I don't normally download games on day 1 at full price, especially ones that I strongly suspect will be buggy but I couldn't help myself - I enjoyed FO3 and FO:NV too much to not treat myself.
(Mods: feel free to move this up a level - there may be folks playing it on a PS4 or Xbone too)
