The game is a whole lot more then just building. There is collecting all dossiers. Tamming all animals. Breeding boss rexes, cave diving for artifacts, boss fights, then final boss. But it is also about mastering all arks.
Never understand why people get so jealous of other side of the game. I have always played on 2 servers. PvE on the Xbox and PvP on the PC. Build, breed, explor, tame what I want on PvE. Kill, pillage on PvP.
