A prequel would severely limit what you could do different with the game, you'd be stuck with the same types of enemies and locations and the entire plot would be restricted by the original game. With a sequel you could explore the human world, face human enemies and the underground could be part of the final level instead of taking up the entire game again. A prequel seems like a pretty stupid idea when it isn't until the events of undetale that things change.

A prequel would just be more of the same thing, only thered  e no branching endings because your chracters doomed to die.

Maybe a sequel that involves time traveling with sans to see how things all began is the best compromisee here.
