We bought our 360 a year ago, specifically so I could play DMC 4. I only just bought DMC 4 a few weeks ago, though. Today I finished it. It was incredibly pretty and a whole lot of fun. My only minor complaint is that Trickster Style in it isn't quite as good as in DMC 3. Switching weapons and styles on the fly and the game mechanics with Nero's hand more than made up for it though. It's definitely worth picking up if you have a 360.
Edit: Yes, this does mean that part of our Valentine's agenda was
a_hollow_year watching me play video games. That's just how we roll.
