Right now these games are set on "easy" mode, you know, for kids. When they finally implement the full game we will be getting a medium and hard mode. Apparently, in these modes you may have to use two cards, pay attention to attack and defense and the RFID chip in the keycard will keep track of your progress. You will "level" up and the cards/spells will become more powerful like a proper RPG. Kevin Yee has a good article/review about it on micechat. I think this is an important step in bringing these Next-Gen attractions to the parks. I also do agree that they should have at least made some attempt at implementing actual props that you interact with. So far all I have seen are curtains opening and closing. We could see something like this in the other parks (Avatar game most likely). I am super excited about this technology seeing as how I am currently studying hyper-reality and location based gaming as a grad student. So much material to research! It will be interesting how they handle the obvious traffic issues in this finite space. The great thing about location based and hyper reality gaming in cities is that cities are big enough to handle the players. Cannot wait to try this out!
