DMC: 10/10. Where it all began, baby!
DMC 2: 7/10. I know a lot of people were disappointed, but I wasn't that much. Though Dante's lines were few, I did enjoy them (King? Right. Here's your crown). This is also by far my favorite Devil Trigger of Dante. Dante's ending could've been better.
DMC 3: 9/10. Great story, insane action, and a new hottie? What more can you want? Besides wanting badly to play as Dante's twin brother?
DMC 3 SE: 10/10 The best since the first and makes up for its original!
DMC 4: 10/10. Haven't played it, but I have got to see gameplay on youtube. Nero is awesome, as is the story, and Lady and Trish look stunning! Not to mention, the action looks as awesome as DMC3!
