PlayerUnknown's Battlegrounds, not to be confused with
@Artist "The New Jesus" Unknown, is a game that I will not lie is fun. However, it's also a game with glaring faults that are integral to the game that will cause the game to be frustrating and ruin the fun for a lot of players and a lot of play-throughs. No matter where you land, it's up to luck whether you find good "gear". I've dropped in "hot" locations and gotten nothing but defensive gear like vests and helmets and I've dropped in crappy locations that most players look over and found excellent gear.
However, as long as you manage to find a gun and you play smart, you can actually make it pretty far. I've played rounds with friends (the only way I'd recommend to play) and we've made it to final three when I went the through the beginning without a weapon and only minutes before the final few circles did I find a rare M4, just to end up dropping it for a less rare AKM because it didn't spawn with ammo.
Another thing to consider is that the game currently only has two maps, although a third is in the works with a snow theme. The Russian map called Erangel is the iconic one of the two and is better than it's younger brother Miramar. Miramar lacks enough loot locations and features too much empty space that'll leave you prone to being spotted and shot from vast distances away. What is cool but also bugs me is that each map features unique weapons and vehicles. All this being said, gameplay can get stale pretty quickly and I find myself tossing grenades at my friends and seeing how close I can miss them with my guns. Maybe in the future when there are more maps in rotation it could keep my attention and warrant its price tag but now things are predictable and I find myself limiting my play time a lot because of it.
Since 1.0, I personally haven't encountered many severe bugs, however in a game where every second counts any bug pretty much becomes game breaking as it can easily get you killed. Playing through it's beta, there were a lot of strange things but I think the game now is considerably polished. Parachutes still need help and the killcam feature is only good to show where you got shot from as the replay isn't accurate enough to show how your killer actually shot you as they always end up shooting behind you in some laggy looking inaccurate recreation.
However, even though I love FPS games I find that PUBG is just an O.K game.
It boils down to what everybody else has figured: it's gotta be your type of game in order to enjoy it and if it is, it'll still be frustrating at times. If your friends got it and you can pick it up on sale, do it.
