Had this one a while ago.

What if some of the humans fell at different parts of the underground? I mean in a logical sense, I doubt they all fell down the same hole (along with doubting the fact that there is only that hole and the barrier), and regardless its just cooler.

Other core cast members could fill in that "Toriel" role, maybe younger variants of characters, fuck, maybe even include something like the amalgamates before amalgamation.

I think this one just depends on how well executed it would be, though. Though hey, maybe you'll surprise people!

Hey, so what if people covered the grounds of what happened before monsters were trapped underground?

Life before the war broke out and exploring the relationship between monsters and humans and how they helped each other could be an interesting topic to work with.

The war itself would also be good to cover, though I feel like having both play out in the same story instead of separate things could make for some really cool juxtapositions.

Maybe it could switch from past (before war) to present (during war)!

Neutral endings. There is, uh, A LOT of them.

Honestly people have probably already pursued them before, but personally I haven't seen any besides one called "AFTERGORE" if I remember correctly, THOUGH I could've butchered the shit out of that.

I mean, this one is quite self-explanatory. Pick a neutral ending that Sans (OH MY GOD SANS) and roll with it! Going into detail on how each character reacts to [INSERT SELECTED ENDING] would be really nice to see, especially the whole factor of [INSERT MAIN CHARACTER] taking the role of king/queen.

Well, thank you for coming to my really mediocre Ted Talk!

We'll be moving to BBC News next as after this goes live I'll be getting the boot.

See you then!
