>>60708611Well, it's small now. During the lead up to MGSV it was huge, but even despite Kojima leaving Konami, the company could've kept it going decently enough, as shown by some spinoffs over the years like Ghost Babel on GBC, Portable Ops, AC!D, ect. Hell, even Rising was a mostly Kojima-less affair, outside of telling Platinum to redo the game from scratch.
Konami just let the IP flounder like a bunch of others by only working on Pachinko machines during this time and only releasing a zombie-themed spinoff
which truthfully was just okay. Nothing terrible.
