Okay, I'm back with my opinion. DC Universe Online is certainly worth a look. It's an enjoyable game and it's the only free MMORPG on the PS3 right now. I recommend that everyone with a PS3 get it and at least give it a try.
@Chang, I'm still playing it if you're interested. I've been through each chapter from 1-7 multiple times and I've gotten about as much as I think I can out of Alucard and Shanoa. I'm using Jonathan for the minute. Pretty good character.
I ended up in a random group last night playing from Chapter 2 to Chapter 6, where we all died against Dracula. I've gotta say, though, playing through it has seriously boosted my strength with Alucard since I got the Heaven's Sword after Chapter 3. And at least I lasted the second-longest against Dracula.
