ya think?
While technically, there's no real reason to like him, I believe that his issued can be fixed with a few minor adjustments.
If you look at DMC4's story, you'll find that it follows rather closely to District 9 (which itself claimed to be adapted from "Alive in Joburg"). but the director himself makes no mention of being inspired by DMC4... it's all coincidental. No really.
Imagine if Nero were the nerdy, yet still arrogant protagonist that Wikus van de Merwe was, and just pretty much give him the same story from there.
Wikus cries, but isn't considered weak (he only does it once, and only after being reduced to eating cat food and having to try to cut off his own arm -- and also after Kyrie -- I mean his wife -- hangs up on him after calling her for help).
The same basic outline is there. District 9 even has the "Phantom Devil Trigger" (the mech suit).
A few changes would have to be made to introduce DT earlier, but it wouldn't necessarily make the story worse.
Also, Christopher is a somewhat silly alien (demon) who wears a red coat... but isn't campy to the point of annoyance. You feel for him, and root for his escape.
I get the feeling that Christopher was named after Christopher Belmont because the director of the movie was a fan of games himself.
And slowly, Nero could end up being corrupted totally by becoming a full demon. Arkham became a demon on purpose... Nero could be a human (or quarter demon, however you want it) who becomes one by accident.
Fortuna could even represent the corrupt government that keeps the demons inside the hell gate/district, drawing even more parallels.
Oh there's even an Angus-like character fascinated with his arm and actually tries to cut it off to gain its power for his own. This is after the scientists do it, so it's obvious that everyone wants that arm.
They need it to control the alien guns/devil arms.
Trust me, if DMC4 (or DmC 2) were more like District 9, it would make for one hell of a game.
Edit:
The bad guy could be this aggressive alpha male jackass who tries to hunt Nero down like in the movie.
Wait a minute...
Joking. Credo was a nice guy overall, but if they had made him more odious, then they could have given us a bad guy that we all would have wanted to see go down.
