I'd say none, because PUBG isn't closely as frustratingly infuriating as LoL or CoD
I'm not surprised by such high numbers. I bought the game as well, just to try it and I was very positively surprised by how much fun it is, especially as a squad of 2 or 3 players. It can be hard and very demanding, but feels rewarding at the same time. If you die, just jump right back in, with a maximum of a minute of waiting between the next skydive.
Try getting sniped when you're in the final circle with only one other player left, and see how you feel :lol:
In all seriousness though, I'm not surprised either. Despite all of its obvious problems (unfair bans, poor performance, unreliable servers etc.), it's a load of fun, especially if you're playing in a squad. I always have a blast playing with the lads in the OC3D Discord.
We had the best game of our PUBG careers last night, proper team work, offence/defence real tactics saw all four of us safely to Nandos for that elusive chicken dinner!
We also have an official PUBG discord for OC3D. Drop me or Wraith a PM if you want to play - we can get you a discord link. We usually have big sessions on Friday evenings
