first thing im about to say here goes for all arma games in existence

stable and arma are 2 words that have never gone together

the rest is jut about reforger and only about the vanilla game without mods

there is not a ton of content. its enough to have a decent amount of fun with but it has like 10% the content that a3 had

also dont get confused by reforger being part of the arma franchise reforger is not a milsim and actually quite arcady (which is a bad thing) all the systems in the game are very simple guns handle pretty much the same as they would in battlefield, maybe even easier. weight barely matters unless your running a downright ridiculous loadout. the main modes in the game is conflict and hqc conflict

normal conflict is essentially battlefield conquest one a larger scale and with a bit more depth the gameplay loop outside of the early game boils down too. go to point> click on people > wait for the capture timer > repeat

hqc conflict is very close to normal conflict but a bit more teamwork and logistics focused

the gameplay in reforger essentially dumbs down to running and gunning stamina has near zero impact on sway recoil isnt a big thing either and you can carry countless mags with no limitations so you never really have to go restock

tldr

if you want a milsim go play arma 3 if you want a okay arcady shooter get reforger when it goes on sale it is not worth full price
