Nightmare, the first Devil May Cry on hard mode was pretty bad. Yet Mundus was a pushover. I wish the original Devil May Cry had a level select option like the 2nd and 3rd where you could play the story on any difficulty at any time. And the 2nd and 3rd games kept track of how far you progressed on each difficulty. You could go back to any mission and farm orbs to help progress on the harder missions. But in the first one you could only progress through one difficulty till you either die too many times until it gives you the option to play on easy automatic or until you beat the story. If you chose to progress further on harder difficulties you really had to get better. Resources were limited. I used up all of my inventory by the time I got to Dante Must Die mode. It gave me the option to go to normal or hard but it defeated the purpose of going back because I'd more than likely end up back in the same situation.
