Okay a couple of things.
First, guys GE argued that DMC3 (no mention of SE, means the vanilla version) has enough content that is surpasses most current stylish action games today. I think you guys have forgotten how much SE actually added to the DMC3. Vanilla version means no Bloody Palace, no Vergil, no turbo mode and no Jester fights (there are probably a couple of other things that I can't remember right now).
I honestly don't think that's a good package for an action game coming out in 2018/2019.
Second, I said it in my initial post that Onechan is low budget. These games are
literally bottom of the barrel when it comes to budget and resources. So, of course they can't compete with DMC on stuff like level design or length of campaign. But still when you consider that the base game has, 4 playable characters each with their own primary and secondary weapons, unlockable accessories, training mode, mission mode (with different difficulty settings) and a lot of cosmetic stuff (the base game alone has like a dozen costumes, there are also hairstyle, cosmetic accessories for each main part of the body, etc) then it's really not far fetched to say that they offer more content than vanilla DMC3/DMC4 did when they launched. And Onechan actually got more of those stuff through DLCs.
Though, I know the definition of content differs from person to person so, some of you might consider styles and gameplay systems (like jump canceling, buster moves, etc) as contents. In that case you are right to say that DMC has more content in its gameplay. Though, I personally look at those stuff as mechanisms and systems rather than contents.
At any rate, moving past the Onechan comparison I still don't see DMC3SE and 4SE as good standard content packed titles for a 2018/2019 game. Maybe my standards are a little bit too high but if I had to chose a DMC release which would have enough content to be released two, three years from now, then DmC
E's would be the one. I think that should be the standard.
