The PUBG game design is very compelling. I think it’s going to become a new classic in the years to come, much like Minecraft style builders or DotA style games have. I wouldn’t be surprised to see a few AAA games built on that model.
The other downside is you spend a very long amount of time looting and exploring only to have it all come down to about 2-3 seconds of gunplay. In those 2-3 seconds you experience perhaps the worst gun combat ever designed. It's very inaccurate, buggy, and frustrating.
The game desperately needs polish. In fact the genre deserves the AAA experience because it is down right exhilarating.
