Gosu AI for PUBG
It never fails to impress me the level of work groups from the PUBG community put into enhancing the competitive scene. First players were given a 2D map replay of their matches to give better insight on movement and hotspots. Gosu ai brings this to a whole new level with mutli-layered data. You can check how you rank among other users, weapon usage, death locations, and more. There is a catch though, and the catch is you need to pay after a free 7 day trial period.
I'm optimistic about the future of this type of service. What tends to happen is some generous individual out there will make their own free version that provides the same features. There's no guarantee that this will happen, but I am hopeful some brave soul will do it.
