Honestly the game feels like a full game. But the way it just ends is pretty abrupt(even for the 2nd chapter). Nothing really prompted the recall and replaying of the prologue. Shit came out of nowher. The game as is has no business segmenting itself in chapters. It makes for criticizing how incredibly truncated ch 2 was even with the replayed missions. It might not be criticized as much but the giant metal gear size plot hole would still remain and that's enough for anyone to feel a little salty. Even moreso when Kojipro straight up says, looks, we had all this other stuff planned to resolve the plot but couldn't put it in for reasons...sorry ¯_(ツI wonder if it was a mistake of them to keep in the chapter screens, would there have been anywhere near as much of a backlash?
