If Japan has an economic meltdown while the rest of the World gets by ok, gaming should be ok, only the big Japan centric companies will be in trouble but it will probably help the big exporters like Nintendo.
I don't think that's what's going to happen though. The world's economic problems are much bigger than Japan, and when the shit really starts hitting the fan the whole games industry will suffer. An upheaval could be good for gaming in the long run, though.
A game I'm developing with some friends:

It is largely a technical exercise but feedback is appreciated.
