Yes, the release of Metal Gear Solid Delta: Snake Eater is a landmark event. The first mainline Metal Gear game post-Kojima, and a remake of a timeless classic. Given shifting expectations of legacy remakes, and Konami's own self-made pressures following nearly a decade of fanbase alienation, the stakes are high for Metal Gear Solid Δ: Snake Eater.
However, whether a success or a failure, Delta will prove to be a turning point for the series. It could prove a springboard for the series' future, or could eliminate one of the world's most iconic stealth franchises, plus once-storied developer Konami, to the dustbins.
For this reason, Konami are evidently taking a conservation-first approach - modern refreshment whilst maintaining a reverence to the source material. Metal Gear Solid Delta: Snake Eater will be one of the biggest games of the year, whether positive or negative.
