anything i should know going into this game?

hey all, i’ve seen a lot of posts around this game and a few comments of people praising it highly and i caved in and bought it. i managed to pick a pre owned copy up for $47 USD with an ongoing boxing day sale which is pretty good i thought. but anyway is there anything i need to know before jumping in, im going to go in completely blind and just experience everything as naturally as i can but just wanted to check again if i need to know anything, thankyou!
