Well a lot of people were a little frustrated with Fallout 4 not having as much focus on dialogue and character. As much as I love this game, I do feel like I was missing out on some of these aspects. A well written machinima that made the story and character really come to life would probably help satisfy a lot of people and feel like it was filling a gap. I'll watch it if it's Fallout 4 whereas I probably wouldn't watch Fallout NV because that game feels complete to me now.
One counter-point though, you may find FO4 a challenge to work with at the moment, whereas NV is much better documented. However the GECK should be coming out soon and make it all much easier.
well, it's no longer Fallout, is it.
It became CoD, or Planetside 2, just single player.
