@Deathstroke lets for example say what if DMC 3 had a super easy difficulty were you can't die
that IMO would not be the same experience that DMC 3 was supposed to be
when i first played the game each time i fought Vergil he kicked my ass
but i never gave up i fought him over and over and got better at the game
i had so much fun with how challenging Vergil was that when i beat the game i seriously felt sad that he had to go
me and Dante both were sad that his brother fell in to the demon world and that we would never see him again
If i played DMC3 on a difficultly where i couldn't die that would remove so much of the emotion i had from that fight
its not that i don't want less skilled players to beat the game
it's that i want new players to have the same experience i had and know Vergil the same way i do
they can do that if they never lose when they fight him
