CvS 2 is simply tremendous. All the added options (customizing game system!!!) are great additions.
Visually, you have to love it. It's just gorgeous. Of course, they added those little things to the backgrounds (like the one rotating platform stage that has Xiangfei from RB2, what's-her-hame from Darkstalkers, and, if I saw correctly, Tung Fu Rue, standing in the background) that just make it that much better.
If I could complain, I would only complain about the game's AI. Sure, I plowed through the game through the normal matches, but once I get to Omega Rugal or Shin Akuma, forget it. I've beat them both now (usually start off at 3 or 4 star difficulty and work my way up), but that wasn't easy. That's not really a complaint. If it's not hard, I don't feel like I get my money's worth.
The survival mode seems to be a bit ridiculous. I'm struggling to get past the 10th match. Once I get that far, it seems like the AI gets smarter 10-fold, and the computer hits a lot harder, too. I get hit 5 times, the match is over. THAT I don't like. I don't want to cave and lower the difficulty setting, but I wonder if that would even help.
All in all, another excellent addition to a DC game collection. Personally, I'd call it a must-buy.
Now, Capcom would guarantee a third in the series...
