Battlefield 1 is the first battlefield game ever made by DICE, however they fooled everyone by releasing it 12 games into the series. This game takes place in alternate World War I, where machine guns are common, everyone has a tank and Zeppelins are the most over powered thing since Doctor Strange in the MCU.
I’ll briefly talk about the single player game, as a Battlefield purist, playing since way back in 1943 (the game not the year), I grew up with Battlefield games being online multiplayers and the single player being multiplayer with bots. The demand for more story driven gameplay is higher than ever thanks to games like Mass Effect and the like giving us in depth stories mixed with engaging gameplay, so it stands to reason that the Battlefield series has started to get their own single player campaigns.
The single player is fine, the characters are mostly relatable if not sometimes a bit bland, but these are modern day game developers trying to recreate the emotions of early 1900s soldiers, there’s a bit of a generation gap there.
The human aspect of the single player is the main focus, telling the stories of ‘real’ people and trying to emotionally engage players like most modern FPS games fall short on. I’ve always found that single player games with multiplayer modes were there to give you a sort of ‘training’ for when you’re ready to go online, and that argument could be made for Battlefield 1. You get to use most of the weapons, drive the vehicles and so on.
