You will see that the game mechanics for Survival Plus is different from the first few seconds in-game!   A lot of the equipment or builds will now need intermediary steps.   The first you will see is hitting the (E) key on plants will now yield plant parts!   And those plant parts will need to be turned into fiber before they dry up and turn into thatch.    But you need a club to work plant parts into fiber.    The bottomline is to forget everything you know from vanilla ARK,  as you are in another world!

And once you get to level 30 and choose a profession,  it seems like your world expands immensely.   You open up your profession worktable and its like you are playing another game!

The page will be your wiki.   Your video reference.   Your profession planner.

Just have to get it done.
