TLDW: Foxhole allows the environment to change in ways other games don't (snow causing direct death, visibility problems, rain causing mud which slows units down etc. ), and also providing options for dealing with these environmental concerns, gives off a realistic war feeling. This in combination with the fact that foxhole allows and requires players to participate in all aspects of fighting a war (material extraction, weapon manufacturing, transport manufacturing, transportation, building of defenses, actual fighting), help provide a feeling of participating in a war that other milsims don't show.
Admittedly, I feel like this game doesn't satisfy what people are looking for in a milsim. Foxhole is a top down shooter, while most milsims are over the shoulder 3rd person or 1st person with a huge focus on tactics and execution. Foxhole seems to pull out a bit more, still allowing tactics planning and execution, but overal strategy and logistics are also added into the game.
yes. kind refreshing to see that it isn't just american influencers that make emotionally charged and shitty content.
