Hmm, I have not seen this before. It looks pretty interesting.
Years ago my local gaming group ran a year long campaign using The Sun Never Sets, which was THE campaign game for TSATF. It was a lot of fun, as each player takes the role of a British Officer and of an opposing force commander in a different theatre. IIRC, I was in charge of South Africa as the British and I was also a Chinese commander in that area.
