seems like only the popular games are removed here

Zelda final fantasy mortal kombat tekken metal gear solid series & resident evil mario games and many other ones are being taken down, the progress is starting to go slowly until they are all deleted.

"Huh?"

Vimm's Lair has been asked to remove many games from The Vault on behalf of Nintendo, Sega, Lego, and the ESA. While most of these games (and the hardware to play them) haven't been sold in decades, ultimately it's their prerogative so these games are now gone for good.
