Well personaly i enjoied the progression from primitiv over modern to scifi. I also always enjoyed building and never understood why the default builing parts didint fit to each others. I remember cables and Pipes which where longer than a wall height so cabeling and pinping was a nightmare. Thats one eason i never played on official servers and only on modded ones (Structures Plus, OzO Craft, Ecos Mods) Without the amazing work of the modders i wouldnt have 300+ hours in Ark tbh.
I dont think i will play ark II if there will be only a Primitive Tier and nothing more. The current solution in Ark is a good one, People who dont like the high tech tier can play the primitiv total conversion or just disable the engrams the dont like. So everyone can decide for him/herself.
But well, we will see.
