Battlefield 1 might only have 5 single player levels
Some developers farm out the story based missions to another team or drop them completely, which is a business decision that must sometimes be neccesary. But the last few years have seen a resurgence in the popularity of well told stories, and blockbusters can't afford to skip the plot anymore.
With that in mind, the early teases of the tale behind Battlefield 1 has looked pretty interesting, not least because EA knows how to make an epic trailer.
