I played DMCs 3 and 4 and loved them, I adore Bayo 1 as well, and started DMC1 recently. It is astoundingly full formed, much less prototypical than I expected a genre defining title from 2001 to be, and it is downright admirable how little story and bullshit there is before the game just throws you in the castle and lets you murder demons.
But the camera is horrendous. I'm fine with static camera angles, I played the other games, but the amount of times the camera snapped around when fighting the lava spider (or the frequent occurrences where the lava spider just jumped in front of the screen so I couldn't see) were very frequent.
Overall it's been a great time though. I'm like halfway through now and I'll be done in time for V.
