So far pretty fun. Will update soon *update* Been playing for a while. I haven't spent more than a few dollars at the beginning and it's going pretty well so far. It seems being in an alliance and participating in all challenges is the fastest "grind" if your alliance upgrades enough you'll get a sweet reward and it's most of a level in Dino upgrades at first. The pvp is good but difficult and doesn't reward you like you'd hope. And I enjoy shooting dinos but it feels unfinished.
