Opinion: Frank Jaeger is the most underrated character in the entire franchise

For real. He barely had any screen time, but for some reason one of the most memorable characters for me. I know there is zero chance it will happen, but a standalone game with him as the protagonist would be cool as hell

One of my favorites. His mystery is part of his allure imo. More screen time could have damaged that. But I still think I would have enjoyed them too. His boss fight in Metal Gear 2 was anti-climactic and silly but his story is interesting.

The VA of him died so Kojima said he won't include him anymore.

Konami could do more for the MGS lore, like how The Joy created the Cobras and became The Boss, the story of Skullface, or even just fix the many plotholes the story have (heck even finishing MGS5 story).

Sadly no one want these kind of things and sales proved it, hence why Konami made this collection and is doing MGS DELTA, meaning that the franchise will probably be dead once we got all the DELTA like for all the main entries.

Granted Konami is so profitable that 1-2 flop wouldn't even be a dent in their profit.
