I've sort of lost track of the main goal of IPv6; what is it?  This particular
thread was about whether it _can_ replace IPv4+NAT, which clearly it can't
given its current capabilities.  As you point out, this may be of no import
whatsoever since IPv6 isn't going to replace IPv4+NAT...

But this is not a limitation created by NAT!  The problem comes about
simply because the ISP is providing only a single public address for
NAT to work with.  If the ISP provided two public addresses then two
people on two machines could play at once with or without NAT.  When
the ISP provides only a single address then only one user can play,
with *or without* NAT.  As I mentioned before, it is a testament to
just how well NAT simulates a routed network that people start blaming
it for external restrictions that it could not possibly work around.
