I haven't played 5, but hope they have slain any roaming dinosaurs.
I'm glad to see more fighters, and more general interest in the PC as a platform. Beyond that I'm a little hesitant with DOA these days. I really enjoyed the theatrics, and visuals back with DOA2 and 3, even paying a good sum to import a version for Dreamcast with more stuff in it. But after just recently trying DOA 4 I was left feeling like I just don't get the game anymore.
It feels kinda shallow, like it is more about characters flying about and dramatic camera angles than much of anything else. I also didn't get the Christie transformation. I thought she was an interesting character in DOA3, and don't see how she went from business suits to S&M and biker gear. There are lots of those girls in games, and they threw away a perfectly good alternative/contrasting element.
Still, I could see picking it up for a couple of bucks some day( am a fighter at heart), especially if it floated into this part of the digital world. But unless someone can explain what I would be missing I'm inclined to not be in any big hurry.
