We're close to the launch of Red Dead Redemption 2, but even if you've already preloaded the game on your Xbox One or PlayStation 4, there are a couple things you might want to be aware of. First, Rockstar has confirmed that there is a "Day-One Title Update" -- if you downloaded then it should be installed already, disc owners will have to wait though. It won't be required for play at launch (remember, there's no multiplayer until a beta test starts in November), but is recommended. It's full of improvements and bug fixes, and if you can spare a few minutes before checking out some ultra realistic horse poops, then it's probably worthwhile. The patch measures at just over 3GB on both consoles.
