/vr/ - Retro Games

What are some games which are direct sequels, but have a completely unrelated title to the predecessor? The only example I can think of is Skullmonkeys, which is a sequel to The Neverhood. Had no idea there was a previous game when I first played it. Any other games with titles that do this?
Bonus points if the sequel is also a completely different genre.

Was Skullmonkeys the last commercial release game to use passwords as a mandatory "continue where you left off" option instead of hardware based save options?

Likewise, what was the last game to have passwords as a continue option, like Rayman let you use a memory card or password, but i seem to recall something in the early days of the ps2 also offering both options.

It only took 16 goddamn years but this shit FINALLY FUCKING WORKS ON PSP

Was this the last great 2D scotformer? I honestly can't think of any GBA scotformers that are worth mentioning.

Is Skullmonkeys good?
I only remember that bonus song that scared the shit outta me as a kid
