I believe that undertale is a superior game because the graphics don't have stretched out textures or derpy shadows.
Story:
Undertale wins because it has multiple endings which proves that the developers actually care about . the story.
Modding: Undertale wins because all Fallout 4 has is a bunch of texture mods! THat's it! Undertale wins on this one.
Questing: Undertale has a variety of quests, but what i don't understand about fallout is that all i see is a bunch of super mutants, raiders, and gunners. no quests. so undertale wins again
Soundtrack: Tie. Both games have beautiful music
I could write more about how beautiful and amazing Undertale is, but I'd rather spend my time getting really immersed in the world of Undertale.
