I would love to see prim+ become part o the main game, hell I'd pay for it as a dlc as well if I had to. I loved the fact that prim+ actually brought more to the farming and cooking aspect of ark. That's mostly the reason I play prim+, because I have all those different seeds and recipes.
I play on PS4 so I have no way to get mods to add new things like that so the fact that prim+ had that, I instantly fell in love. The fact that it's pretty well been abandoned though sucks, it's a great change from the race to Tek that Ark has pretty much become now.
