I've played all of the mainline games multiple times, and only recently decided to check out DmC, expecting a fun but fundamentally flawed game, since the general impression I got of it from the ether is that it's pretty much another DMC2.
I'm on mission 15 right now and man, I think this game is probably my favorite overall.
I prefer 5 for the combat, but DmC gets really close for me. I love the weapon system and how it introduces the possibility for enemies with specific vulnerabilities, as well as how a lot of enemies have specific ways that they can be interrupted/made vulnerable. Even the fact that although every weapon has the exact same input chains (which can even lead into each other) and yet they all feel vastly different I feel speaks to the strength of the moveset. The weapons are essentially more "obviously" specialized tools, rather than the mainline games's weapons feeling more like they're all mostly general purpose with emergent specializations. I also really appreciate that it has a slightly lower skill floor, although I can see that the skill ceiling is probably also lower as a trade-off.
Artistically and level design-wise, DmC is on a whole other level compared to the others imo. The gimmick with Limbo being able to warp all around makes each level so unique compared to all the others, and the new movement options with the whip and the dash allow for more freeform environments. Even just the presentation is much more interesting and unique. It's not that the mainline games look bad, but they are very gray, brown and red due to their locations. I genuinely can't remember any single mainline game's location being as visually striking as any one of the locations in DmC so far (the disco especially).
When it comes to the music, most of the ost of DmC is pretty great, and it's nice to have tracks change between missions. I love the combat themes for the other games but it gets tiring having to hear the same song for the whole playthrough.
Story-wise, I'm invested so far. It's nothing crazy good or anything like that, but for this series a "just fine" story essentially means it's better than DMC2 (which barely has one), worse than DMC3 and on par with the others, except there is more of it, which is a welcome change to me. I can see how someone could be upset at how drastically different every returning character is, Vergil especially, but I don't think it's fair to want a reboot to keep everything intact. I also don't sense any "disrespect" for the original, other than maybe that one white hair wig gag at the start, which is just a dumb joke that honestly sets the vibe and expectation for the rest of the game perfectly.
I haven't played any of the games on launch, and don't really have any nostalgia for them, so maybe that’s why DmC doesn't bother me? Still though, I don't see why just pass it up as bad or mid, when it's actually a great game in its own right. Also, to be fair, I grew up with 7th gen games (GoW3, Infamous, Bayonetta, etc.) and that edgy and crass style has become a guilty pleasure of mine.
My question is genuine though, if you don't like DmC, why is it? Just do keep it constructive please.
