Downward Spiral.
I couldn't ever tell you that Vergil's Downfall is a terrible piece of content - it's certainly not. What I can tell you is that is did not enrapture me as much as the main storyline. Vergil's strengths in combat are completely different from Dante's, and I'm glad this is the case. You can easily tell they are brothers by the way the characters control, however, in an obviously biased belief, I had more fun as Dante. This can easily be the opposite for anyone else, which is one of the reasons why I think this should be played by any DmC enthusiast, however, I didn't hit my stride with the character until the last mission of the content. Of course one can certainly go back and replay this 2-hour long chunk to really fine tune their experience - this just isn't the case for me. The actual narrative is one of redemption, and is a story worth telling, but could have tied in more pertinent themes found in the main experience. The storyboard nature of the cutscenes feels a bit on the rushed side, though it doesn't detract too much from what the player is visually accustomed to. If you're a fan of the reboot, give it a go - the mechanics are still as solid as ever. I'm just saying that this might push you back to more playtime with Dante, but hey, that's still one hell of good time.
