Like Xer said - you’re using simulation as a play on words, and ignoring the fact that “Mil-Sim” is not a subjective term, it’s an already established genre of video games.
Call of Duty Black Ops 3 also “simulates” real life sprinting - but it’s not a MIL SIM. It’s an Arcade Shooter through and through.
There are very few people that are arguing “That can’t be added because this isn’t a mil-sim” to suggestions that don’t make this game more “mil-sim”-like. The majority of the people using the “this isn’t a mil-sim” argument are people arguing against suggestions like Sniper Rifle OHKs to the chest at long ranges, putting gore into the game because “explosives blow people to pieces” while intentionally ignoring the already established revive system, arguing that nobody should just be able to parachute mid-air whenever they want because real soldiers don’t all carry parachutes, you shouldn’t be able to blow up a tank with two small blocks of C4 because that doesn’t happen in real life, stingers should one-shot helicopters because they do in real life, FLIR should be able to see through smoke because it can in real life, even though it creates a camping epidemic on tighter-quarters maps, etc, etc, etc.
People who suggest sacrificing Battlefield’s CORE gameplay, that’s been established for over a decade, for something more “realistic”.
There are an increasingly larger number of people that seem to think this game is closer to being PR and Arma than it is to an Arcade Shooter, and that’s not the case at all.
In that regard - to keep Battlefield in it’s arcade shooter roots it’s had for 15 years - the “it’s not a mil-sim” argument is absolutely valid.
“Mil-sim” and pure “simulation” are not the same thing. You’re mistaking a game genre for /actual/ simulation. Battlefield has never been a Mil-Sim. I’m willing to bet there are significantly more people in the community that agree with that than there are that will actually admit that they think this franchise is a mil-sim franchise, probably including some mods and devs.
Simulating human sprinting in a video game =/= the video game being a Military Simulator game. Other than movement in this game - what else is even remotely realistic, more than it’s just authentic to real life? The shooting isn’t, the bullet velocity isn’t, the damage model isn’t, the way vehicles operate isn’t (one man tank army. woooo), the way helicopters fly and react to the environment around them isn’t, explosives aren’t, destruction isn’t, vehicle physics aren’t, collision physics aren’t, the revive system isn’t, the ammo refill system isn’t, the medkit system isn’t, the selection of weapons compared to the nations you’re playing as isn’t, etc, etc.
Those are more “authentic” or even “semi-authentic” aspects, which includes the majority of aspects of this game.
Please - name me things in this game that are purely realistic, rather than solely authentic in nature.
