DMC4 is really funny. Maybe a little bit easy in the first available difficulty levels. Dante is cool and very funny, and the gameplay is really amazing and smooth. Not a perfect game, not the best DMC, but is a good game
One thing I wished they did for DMC4 was to allow Trish to be unlocked on Dante's missions (similar style or could have used DMC1 style) and then have Lady unlocked for Nero's missions (kalina ann's chain and knife takiing the devil bringers place)
The game did feel off, not knowing it was rushed/unfinished at the time, but I liked it. 3 is my favourite gameplay wise.
And I did like DMC2, in the UK DMC2 was better than DMC1. 50hz slowdown ruined gameplay and the controls being so bizarre (triangle to jump was not natural at all and I don't think you could change the buttons round)
I might pick up HD collection to see what its like playing it full speed though, will more than probably make it better than DMC2 then.
I loved playing as Nero. In fact, DMC4 was probably the only hack and slash I've played where I enjoyed using the character with a limited moveset over the character with a bunch of moves at his disposal.
Trying to master exceed and max act alone made that character so fun to play as. Plus some of those buster grabs were pretty satisfying to pull off. And though Nero was limited to one style of play, he had enough variation in his moveset to make it feel fun without becoming too repetitive.
Dante on the other hand had so many options at his disposal that I was honestly overwhelmed with the possibilities. Granted, that's not to say I hated his style of play in DMC4. On the contrary, I respected it greatly. And it was nice to see the developers offer players a character with a skill ceiling as high as Dante's. I personally just never developed the willpower to get comfortable with him since it seemed like a very daunting task. I admit I also got caught up with all the fun I was having consistently executing max-acts throughout the course of my attempts to set records in Bloody Palace.
Backtracking sucked, but I eventually got over that once I accepted the fact that I was playing DMC4 primarily for the combat system. And to that extent, I ended up enjoying this game more than DMC3. I felt Nero ended up being the only character I've played in the genre with a skill ceiling that came the closest to matching my own.
