It fleshed out the story a fair bit. It's the hardest one and has the most amount of content in the series.
Although my favorite is DMC4, because that's the first one I played and then I went backwards.
i same started with dmc4 and i love it, i just finished hd colection few hours ago and was rly disapointed with dmc3 it is hardest and story is much better then first 2 but still they love it and hate reboot bec dante is different but in my opinion he have much bigger personality then one from dmc3,
idk is it bec its a old game or something but to me he was somehow cringy
