In terms of immersiveness, for me mas okay to do a "blind-playthrough". Walang reference sa lahat no google, enjoyin mo entirely from scratch and explorin mo options na gusto mo. Besides, if you have time pwede mo naman din ulitin and try a different path.
(if this doesn't convince you, try mo iroleplay imaginary yung character mo like ano bang gusto mo para sa taong 'to and stuff)
Goodluck and enjoy!!
