Epic observed the fails from H1 and PUBG and are not making the same mistakes, they are staying active seeing what people want constant updates and new content. Also they have stuck to 1 map expanding it instead of releasing a new map and splitting the community into 2.
PUBG could of been the better game but to little to late for them in my opinion the game is boring as **** to watch and also to play if your average your just hiding / healing in gas to place decent.
