Hey there guys.

I played and fully finished GTA V last year because I've always loved the game series but after watching some Youtube videos I found out I missed some things (which later got me into the full completion of the game) and some "returning player" features I didn't wanna skip on.
My question is, since I don't have a PS3 and would kinda like to play the game again and this time around not miss on those features, is there any easier way to be a returning player?

Appreciate the help. Thanks!
