It has been slowly coming out that the Master Chief Collection will have a 20GB day one update, ontop of the 40+ GB the disc content has. This is because the 4 games are put onto 1 disc, as Microsoft believes that two discs are "impractical."
This means that people will need to find an internet connection to play the game, so if you don't have internet get to a starbucks early!
What do you think? Is this a good idea? Let us know in the comments below!
