For me, MGS1. The tone of the game is really helped by its limited detail. It has the dark and serious mood throughout the game that just permeates this looming threat that is Metal Gear and the mysterious Foxhound unit. I think Twin Snakes doesn’t look nearly as memorable or unique as MGS1 and I think a modern remake would lose a lot of the tone and atmosphere that the original had.

Oh and the artwork for MGS1 is just so incredibly good.
