Pros:
- Immersion
It can be overwhelming at times but its what I imagine the chaos of war would actually be like
- Realistic (ish)
No weapon attachments like cod or battlefield, factions use historically accurate weapons and tanks, TTK is realistic and if you don't seek cover you'll die randomly.
- large maps
- 100 player games
Cons:
- Huge learning curve if not use to mil sim games
- Tutorial / basic training is lacking
Things to be aware of:
- This game requires a lot of communication between other players, if you don't like talking or listen to orders expect to loose a lot or get yelled at by other experienced players. (Most players will help explain things if you are new and willing to learn)
- watch tons of videos on YouTube to learn how the game is played
Overall best FPS / war game I've experienced in my 20 years of gaming.
