Arma Reforger is a nice tech demo for the Enfusion Engine. The only problem is that the built-in workshop is a disaster. I don’t know if modding was a major priority for Bohemia Interactive in the past, but for Arma 4, it would be nice if they went back to using the proper Steam Workshop. Maybe they should ask the developers of DayZ. They do a pretty good job with it.

Its not as good as Arma 3 but its a nice new fresher feel. Feels slightly more realistic but still runs a bit rough on the fps and CPU. Dont expect mega frames or stability or even to last a full server match. You may get 90 fps, you will definitely game frame drops below 60 and you will be occasionally disconnected from the server without reason but it will join back and you should spawn exactly where you were.
The wait times for sever queues is up to 10 minutes often but its worth it. The file size will increase because most good servers are full of mods (which auto download as you join) and can go up to 20gb (My game file is 70gb)

Controls are complex
Graphics are decent even when you have to run them all on mostly low-mid for fps
Plenty of communication and friendly people
Tons of servers for all regions and languages
People are friendly to new players but I recommend the tutorial as it will teach you some valuable stuff before you first go into a conflict game

Mostly...just enjoy it. You may spend 30 minutes trying to run into combat only to be instantly die from a sniper but you will get used to it. Take your time, think smart and just have fun

It's the same Arma experience, unoptimized, clunky and on top of that, it runs like ♥♥♥♥ while looking average as hell. Don’t believe the screenshots on the store page because they’re heavily downscaled.
I’ll maybe give it another shot in the future if it’s heavily discounted, but right now it’s just not worth it and lacks optimization.
