You are missing the point i was making in earlier post. Replaying through missions through higher difficulties is the same as backtracking missions by playing as dante. The difference is enemy patterns are different and aggressive on higher difficulties but when played as dante, the character played itself behaves differently to enemy patterns. So playing through levels as dante is jus as similar as playing higher difficulty with same platforming sections and level design. So why complain on backtracking when playing higher difficulties with the same level design.
Because there's a difference between higher difficulties and being forced to completely retread Nero's entire journey as Dante in order to reach the conclusion of Nero's actual journey. You literally cannot complete the game and fight the final boss with Nero without having to play as Dante and backtrack all the way through the game.
The complaint is about the laziness and the lack of originality of it all, not the difficulty.
Defending that you are not forced to play higher difficulties is as subjective as completing the story mode. The game does not end with completing jus story mode on normal difficulty. If you can choose to not play higher difficulties, you can as well choose not to play backtracking missions as dante, well the reason being the level design and bosses are the same to you.
Again, playing on higher difficulties is different from actually completely a game. To see through the single player mode the devs put in the game in order for you to experience all the different levels and enemies by forcing you to go completely backwards through everything with a different character is the laziest form of backtracking and "play as a new character" feature I've ever seen. A single player game "ends" when you've completed the singe player mode, you can go back and play it as many times as you want, but you're
always going to have to deal with that sh!t backtracking.
It's no different than being annoyed with game padding like having to fight Master Copies in old Mega Man games (or even friggin' Metal Gear Rising). OH! Sh!t, I forgot! DMC4 has that too! They make you play that stupid-ass dice game again, where you can be forced to fight the bosses of the game again before you can confront the final boss!
Here's a question, If dante were to have different enemies and bosses, would that not mean a different bloody palace needs to be developed cuz dante's bosses need to be played differently than nero?
I don't see what the point is - I'd love that for DMC4. I would have
loved for the dev team to not have taken the easy way out with having to playable characters. Not when they previously had a game on a less-powerful system that had two full-fledged characters with their own story modes of the same length. Instead, we got the half-assed "here's the new guy" who doesn't get any other weapons, and here's the old guy, but we split up the campaign between them.
It would have made the variety between the characters more apparent, and how they fight their unique enemies. It also would have been a
much more interesting campaign to see what Dante was doing around the city during Nero's playtime, instead of passing the controller to Dante for half the game.
All in all, the problem I have with what you said is that it still boils down to you saying that "nobody is forcing you to play through the entirety of the game, so you don't have the right to complain about what in it."
Sure...jus' lemme spend my hard-earned money on games and then stop playing them when I reach a point in them that I don't agree with. That's the responsible thing to do.
