I have been playing PUBG for 2 years now and from as far as i can tell it's a really fun game, but of course it has it's issues like bugs, etc. Anyway i never experienced a major bug beside the vehicles that crash into really small objects.... For now it doesn't have the best optimization, but Krafton is working hard to make this game better and better and they already did major changes like there are so much less cheaters (actually i never met one, i'm playing in EU), and also they optimized it a a bit, and they are planing doings so again. It's also a complex shooter, because there is a variety of weapons and mods that will be bigger in the future. Also it provides big maps which is a great feature. It's also nice that you can drive a variety of cars that will also get bigger with further updates. It's also great that we can play both Third Person and First Person(better for low end pc gamers).
With that being said, i highly encourage you to support PUBG and look into the future plans of this game and give some trust to Bluehole, which is a small team trying to rise with this great game, that is surely intense, realistic and fun!
PS: I know it's not really worth a 10(for me it is 10/10)but i really Krafton will optimaize graphic settings in the future. :)
