hey Zee, so i will explain it in a gaming terms. 𝟭𝘀𝘁 𝗽𝗲𝗿𝘀𝗼𝗻 refers to "we, I", so it will show your hands such as fps games. 𝟮𝗻𝗱 𝗽𝗲𝗿𝘀𝗼𝗻 refers to "you", the reason why there's no 2nd person game is, the pov is a mix of the 1st person looking at "you" like a 3rd person. Lastly, 𝟯𝗿𝗱 𝗽𝗲𝗿𝘀𝗼𝗻 is like GTA games, where you can control "them, they" and you can see their back for example. does that answer the question?
