Metroid Dread is a such a great game, I can't say enough good things about it! The controls are so polished, and the bosses are pleasantly challenging. I would have loved to play more games like this as a kid -- I didn't realize how cool Samus was.
They must have spent forever on even the tiny details, like the way Kraid's claws regenerate as he snarls at you. And I especially enjoyed becoming a BIO-HORROR.
I loved the Chozo characters, and the E.M.M.I.s were so creepy. It truly was a Metroid Dread.
