I mostly go for the authentic experience but it really depends on the game for me, there are some games I play straight thru without looking anything up and for some others i got gamefaqs loaded up right next to me the whole time.
for example, two games in the same series, chrono trigger and chrono chross, both fairly lengthy with multiple ending.
when i played CT a while back (which if u don't know is the first one 16 bit classic go play it) i just went with it got a good ending (idk if it was the best or not but w/e) and moved on,
when i just recently played Chrono Chross however my friend had told me about all the characters (40+ total i think) and how u could only get about half in one play thru and could just miss some so i used faqs to make sure i got the characters i wanted even tho i made decisions i would have if i played authentically and still enjoyed the play thru
