We were trying to figure that out in the thread. The answer seems to be "not exactly, but there are some similarities."Is this even anything like the Gamecube one (only one I played)? What they showed made it seem more like some kind of AR game.
The big picture is that you do the AR thing, but to earn the film for the AR thing, you explore some environments and help out some characters. I don't expect it to be as great and definitely not as expansive as the original game was, but I think the spirit will be there.
Skim the thread I linked, should be helpful. We found several gameplay videos. Demo will be out today too.
