The game just had an update to support the Switch 2 only 2 months ago. It is still being used commercially.

Konami willing, they'll drag the IP to their grave. Lest we forget MGS3's first remaster... for Pachinko parlors: https://www.youtube.com/watch?v=VsJ4QgBpQN8

Recompilation efforts raise the bar for future re-releases, and incentivize proper remaster efforts like MGS Delta instead of the half-assed Master collection. I would love to see Konami thrive as a company and get more people interested in MGS, but their recent re-releases don't deserve to be priced at $60. Their monopoly of the source code feels like an existential threat to both future preservation and high-quality MGS remakes, it's healthier for Konami to simply let it go at this point.
