Geoff Bohrer offers a postcard game — an entire Avalon Hill style game on a postcard — of the Japanese invasion of Malaya:
The Japanese invasion of Malaya was one of the most perfectly executed military plans in history. Can you, as the British commander, slow the Japanese advance sufficiently to disrupt the timetable for the capture of the East Indies? Or will the Japanese succeed in capturing Singapore in time to establish the Greater East Asian Co-Prosperity Sphere?
This 5×8 inch postcard game includes 18 counters, complete rules which include the asymmetrical abilities of the Japanese and UK forces,and a 5×5 1/2 inch board.
