Bf1 is just 4 with a ww1 skin. Literally the same animations and shooting. Only reason it even has the hype it has because people want more reasons to hate on COD.
Halo did space, double jump and all that shiz way before titanfall and COD. And BF1 will rip all fps asses.
Did you just accuse a video game of not being "realistic"? Because CoD is incredibly realistic right? Because FPS blockbusters are realistic right? Dice even said that BF1 is being set in an alternate WW1 scenario, not exactly historically accurate to allow for more creativity. There were lots of theatres of WW1 over the 4 years it spanned and the fact it occured over the entire WORLD, not just the trench warfare such as the Battle of the Somme. Are you just trolling now?
WW1 was pretty much just trench fighting. If they try to bend the rules it won't be realistic.
Where have you seen it is going to be mostly trench fighting?
