Usually it's easier to match what you want to keep instead of splitting on the stuff you don't want:

#!perl -w
use strict;
use Data::Dumper;

my $string=q{C*ID1*Mac*C release for EA's D*ID1*Spore1 game*D; D*ID1*S
+pore 1*D is better than D*ID2*Spore 2 game*D.};

my @sections;
while( $string =~ m!(([CD])\*(.*?)\*\2)!g) {
    push @sections, $1;
};

print Dumper \@sections;

__END__


$VAR1 = [
          'C*ID1*Mac*C',
          'D*ID1*Spore1 game*D',
          'D*ID1*Spore 1*D',
          'D*ID2*Spore 2 game*D'
        ];

The regular expression looks for a C or D followed by a * and then slowly goes forward until it finds a * followed by whatever it matched at the start.
