Bloody Palace > that few hours of the game you get to play as Dante in regular 360/PS3 DMC4. Bloody Palace is DMC4. which is not a huge consolation, but it's a part of the game I've been able to play for years and not really get bored.
On PC, you get Legendary Dark Knight mode, which is fucking nuts and way fun to play, though with that many enemies you're bound to take some cheap shots. It can get quite tough. You can't just use 2 combos and survive unless you wanna spend the whole time perfecting rolls and your reaction time, which would be impressive in itself.
If this is just a PC port w/Vergil, I'd be happy with that, but I think they'll do something more than just plopping Vergil in. With the way that game turned out, there has to be some cut levels they could polish up and add back in. If LDK mode doesn't make it in, I will be pissed.
This is coming from someone whose PC copy crashes at random on both DX9+10 modes. More so on DX10. so getting a non-crash version is all I really care about.
