The game is good, it brings the best aspects of world and rise.
The game story mode, low rank and high rank content is great, a fun introduction to new monsters, every monster is unique to fight and is generally a fun game!
But end game content? Theres unfortunately nothing much to do, even limited event quest, it doesn't offer much than, hunt this arc tempered monster and double ur hr points, etc.
Honestly, for now wait for the expansion dlc, ur not missing out on anything playing the game this early in its life.
