Undertale really said "what if an RPG made you feel genuinely bad for grinding" and changed everything. the genocide route is still one of the most psychologically brutal things ive experienced in gaming. Sans dunking on you after 50 deaths while Megalovania plays is peak game design. but honestly the pacifist route ending hit me harder emotionally than most AAA games with 100x the budget. Toby Fox is a genius and Deltarune cant come fast enough.
