Thats not to say that Disney can't learn from D&B. It just proves that arcades can survive and be profitable in today's xbox360 world.
Once you pay to get into DQ you get to do just about everything in there for FREE. For the price of a DQ ticket I can enjoy myself at D&B for about 3 hours. DQ has the VR games that D&B is lacking (at most of it's places) and the layout of that place is awsome. Inside DQ you really feel seperated from reality, like your in a cartoon.
Another thing is that they don't really play up the big attractions. A lot of people don't know that it is there and if they do they can't name any of the games that make it special (cyberspace mountain, pirates, ect...)
I say add a nice place to eat in keeping with the wild theaming, update some of the games, maybe have some tournements with the old titles (I am the KING of Joust and I need a place to prove it), and advertise the thing.
Again this is comming from a mega geek, I freakin need video games.
