I haven’t bought any expansions and find there is more than enough to the main base map than I could ever do. Until the raptor sneaks up on you and eats you that is… Online as a PVP, it would be mostly combat, but offline PVE like I play, it is more about survival, creativity, creation, exploration, and just relaxing casual fun. I don’t and if I tried then my base would definitely get raided during the day when I am at work or when I am asleep. If you have hours a day to dedicate to this then try the online PVP. If I played online then yes, it would be an MMO with a lot of grinding and would then make it a PVP (player vs player). I’ve only played it offline and single player making it a PVE (player vs environment).
