There's one significant difference in most other countries; we allow plenty of immigrants. Here in Ireland we have many thousands of Poles arrived in the last few years (10% of our pop are fairly recent immigrants), which have slowed our decline in Catholicism among other things.
So I don't think Japan is as much a predictor as Malstrom does (his belief is based on pop decline).
A game I'm developing with some friends:

It is largely a technical exercise but feedback is appreciated.
