I used to comb most maps for secrets in the past but I found it's simpler to just take the shortest path. I am sure I can survive without that silver dagger or an extra tonic.

I only scavenge for stuff if I am being beaten hard which hardly happen on modern games. I think the last game which made me want to look for extra stuff was Dead Space but ironically, a ship full of necromorhps isn't a inviting place for exploration.
