Pros:
+ The Best Strategy & Teamwork Game or just Battle Royale (Better than H1Z1 and Squad)
+ Not very expensive (only $30 USD, compared to games like GTA V, Squad, etc.)
+ Loved by the whole community (It's the most played game on Steam!!!)
+ The devs try to listen to the player base, although they are struggling with the chinese cheaters, they have slightly reduced them and the cheaters won't affect that much the casual players
+ Frequent updates and solid developement
+ You can have MUCH fun if playing with friends
+ The random gun spawns are ridiculous xD

Cons:
- I don't know if "killing a streamer" is illegal anymore and gets you banned, but the only good streamer who doesn't cry when he gets killed is Shroud <3
- You need at least mid-tier gaming desktop PC (Well, I can rush everything on Ultra at constant 80-90 frames *up to 100 sometimes* but it's not worth it because you would play the game itself or just look at your skins?)
- They ban you *temporarily* for having fun with your friends while teamkilling them (like CS:GO...)
- Requires much practice, but it is understandable (be prepared for similar recoil to Escape from Tarkov's, if you have not been very good at FPS games at all)

Update: PUBG has come a really long way all the way back since early 2017 (when I also joined the game) and it has been mostly a positive change. The game retains the same more realistic feel of movement and gunplay, meanwhile the color gamma of the game has changed and most maps have been remastered (I miss OG Erangel the most tbh). Much more content has been added and PUBG is already diverse enough to be enjoyed thoroughly and the performance has been drastically improved, so it runs smoothly. TBC
