Not really my point but whatever.
In terms of Prim plus, it is an official mod released with the core game. For those of us that play on xbox and have no access to the mods that PC does, we can still play prim plus.
As for this game. When I first started playing this game, it was a survival game with dinosaurs. Aside from the implants and arks, there was no heavy futuristic sci fi feel to the game. That was the game I actually enjoyed. As they continued to develop it and changed the core fundamentals of the game into the heavily futuristic sci fi game it has become was when I started to lose interest. I still played mind you, but the game isn't as enjoyable for me now as it was when I was first playing it in preview (pre flier nerf)
