Buried In Time: Another World 2 - Éric Chahi wasn't involved in Heart Of An Alien and has disavowed it. Now that he owns the IP, I'd like to see what he'd do with a sequel.
Castlevania: Symphony Of The Night 2 - If Koji Igarashi returned to the franchise to make a sequel to the original.
Cave Story 2 Chrono Trigger 2 - The Dream Team reassembles to make a direct sequel to the original game.
Donkey Kong Country 6 Full Throttle 2 Hades II: Mount Olympus - Zagreus must take down the Olympians.
Half-Life 3 Hollow Knight: Silksong La-Mulana 3 Max Payne 4 - Especially if Remedy Entertainment returns to work with Rockstar Games.
Metroid 6 Metroid Prime 4 Portal 3 Super Mario Bros. 4 Super Mario World 3 Windjammers 2 I pretty much have a similar taste as Shadow Man. To buy possible future games like Another World 2, Castlevania: Symphony Of The Night 2, Full Throttle 2, Metroid 6, Super Mario Bros. 4 and Super Mario World 3 would be a no-brainer for me. Furthermore, I'd love to see sequels for Return to Monkey Island and The Fate of Atlantis. It's about time we get a brand new Indiana Jones point and click adventure game, especially now that the final entry with Harrison Ford in the film series is coming out. That'd be awesome!
