If Dincrest can't compare something to metal it's not worth comparing :P
Or food. I tend to use food analogies just as much, if not more than, music analogies.
Anyway, though I won't be playing P5 (for aforementioned reasons and the lack of a PS4), I am curious how the scenario writers will work the anti-hero thing. A good anti-hero is very tricky to write, but when done well, we love it.
I remember with my second P3 playthrough, I tried to make my protagonist an idiot slacker, but doing so locked me out of everything, so I was forced to make him a Marty Sue. So how will such play mechanics work in terms of creating an anti-hero?
