One thing I've never done with a Bethesda open-world game is get right to the main storyline. I spent 500 hours in Skyrim before I decided to give a shit about Alduin, I spent 1000+ hours in Morrowind, and I never did finish up Fallout 3, New Vegas, or Oblivion. When I first started FO4, I didn't give much thought to its story, either. Dead spouse and kidnapped baby? Meh. Plus, I don't care about spoilers, so I already know the big twists and turns in the narrative. But Kellogg hooked me. There's just a lot of "why?" and "how?" involved with him and the Institute, so I've played through about half of the main story now, without getting too distracted by any side business. I really do hope some of the "why?" and "how?" questions get answered.
I'm also playing No Man's Sky, which I bought on sale a few weeks back, in conjunction with the much-lauded "Atlas Rising" update. I don't mind saying, this is the space exploration game I've been looking for for years. I'm glad the developers stuck with its development, and it's turned out to be solid. There is a very good chance that I will spend a whole lot of hours on this one, just exploring, logging discoveries, and collecting stuff. The only problem is that planets really get laggy on my aging laptop.
