Almost gave up after a few minutes because of the dated controls and punishing save system, and used a guide like any sane person would. But sticking with it was a really rewarding experience. A great time capsule to see what games were like about 40 years ago. Imo, it's an absolute masterpiece from Kojima. Yeah there's a lot of backtracking and annoying things but thematically it makes sense considering the plot twist. A lot of people skip this and Metal Gear 2 but if your introduction to this franchise was through MGSV (like me), these two games should not be avoided.
