The Day One patch is an inevitable part of gaming these days. Just about every title that hits store shelves will ask players to download an extra update before they can actually play the game - and, while these patches are important, they're usually pretty big, too. There's nothing worse than waiting for a game to install and then realizing that you'll have to wait for another few hours before you can actually play it.

It's no surprise that Fallout 4 has a Day One patch of its own - Bethesda games are always huge, and updates are a pretty regular occurrence. Considering the game's size, it's easy to assume that Fallout 4's Day One patch would be absolutely massive - in actuality, it's not all that bad.

If you've bought Fallout 4 for either the PlayStation 4 or the Xbox One, you'll be prompted to download a patch as soon as the game is available. While the core game may take up 40+ GB of space, the patch itself is relatively tiny: the update will only take up 500 MB of space.

So, what exactly does the patch do? Well, Bethesda isn't being all that specific: supposedly, the patch helps optimize the console versions of the game for launch day, but that's about all the publisher is willing to reveal. It's about as generic as patch notes can be, but at least the update won't take long to download.

Sure, Day One patches can be a bit obnoxious, and Fallout fans have been waiting for years now...but things could have been a lot worse. The smallest version of the Day One patch for Call of Duty: Black Ops III was 2.7 GB - that's basically an entire indie game just to get the game running.
