E3 has been chocked full of announcements about Bethesda Game Studios’ latest project, Fallout 4. One thing that I’ve been pondering on recently, however, is how long this game will be.

When I played The Elder Scrolls: Skyrim I sank at least 150 hours into the game before I even got around to completing the main quest, there was so much to do and see. I thought that game was huge and endless.

Recently I’ve been playing Witcher 3: The Wild Hunt to hold me over until Fallout 4 comes out in early November this year. While I have not finished this game I have played 50 hours of it and I feel like I’m only about halfway through the game. Reports from other players and developers at CD Projekt Red have said that the game should last 200 hours if the player intends to complete all quests.

I thought to myself that Fallout 4 would be similar, maybe a bit longer. However according to Jeff Gardiner, the lead producer on the project, the game is at least double that at 400+ hours.

This opens up a whole new line of questioning for me as it answers one that I’ve been dwelling on. How big is this world? How many main quest lines are there? How many possible endings are there? How many times will I have to play this 400 hour game before I see everything?

One thing I know for sure, I can’t wait to spend the next 10 years playing this game as thoroughly and completely as I possibly can and I will enjoy every minute of it.
