I actually like unlocking harder difficulties, it feels sort of rewarding for me.
I remember finishing DMC 3 on normal... and unlocked hard, then finishing it on hard to unlock Dante Must Die and finish that to unlock Heaven or Hell. I had a lot of fun playing and re-playing the game over and over again from the beginning and the harder it got the more rewarding it felt... and you also unlocked other stuff appart from new difficulties like costumes, videos, screenshots and things like that.
God Hand was pretty cool with that too... I remember finishing normal and having some trouble to do it only to unlock Hard mode, which was like hell the first time, lol... I even thought I wasn't going to make it xD pretty awesome :D... too bad there wasn't anything harder than hard... so I had to re-play it with self imposed challenges to make it harder for myself :P.
I remember other games like Megaman Legends 1 and 2 i which you cleared it on normal to unlock hard and after finishing the hardest mode, you unlock Easy mode... it's cool and you feel overpowered but... I don't know, it isn't as rewarding as getting a harder difficulty.
I had no problem getting all weapons and stuff in that game over and over again, it didn't bother me.
