MGS for sure. Six quality games (the one I'm omitting is TPP), with three more if you do the original two and Rising.

Then Ass Creed. People crap on it, and rightly so, but if you haven't played any of them, you should definitely pick up 1 and 2 at a minimum. 3 and 4 are also good, but the first two are really where it's at. Note that I skipped all the side games. They're worth a play if you liked the others but they're not anything standoutish in terms of gameplay. Just make sure you stop after 4 and Rogue, because Unity was garbage.

Up next, Kirby. Lots of them are skippable, honestly. If you've played Adventure, you've played most of them tbh. But the ones that are must plays IMO are Superstar/SSU, Planet Robobot and Canvas Curse.

Tales... has good highlights. I've disliked more of these than I've liked. The pacing tends to be atrocious, so I eventually gave up on the series. Though I personally do recommend Abyss and Vesperia.

Uncharted is the vidja equivalent of MCU. It's all spectacle, but it's fun spectacle. I do recommend them, but only after all of the above.

The rest, I'm not really qualified to speak on. I might have played a few titles here and there but that's it.
