Here is the “object of the game” from my rules:
The Battle of Midway is a two-player game with one player controlling the U.S. forces defending Midway Island and the other player controlling the Japanese forces attempting to sink the U.S. fleet and invade the island.
While the U.S. faces grim odds in this battle, they have one major advantage � they have broken the Japanese radio code. They know the location and makeup of the Japanese forces; while the exact location and makeup of the U.S. fleet is unknown to the Japanese. The Japanese must first find the U.S. fleet before they can attack it, while simultaneously protecting their carriers from the inevitable counter-attack by U.S. aircraft.
For the U.S. to achieve a decisive victory they must sink 4 of the 5 Japanese carriers, matching the success of the real battle. Sinking 3 Japanese carriers or any combination of 4 capital ships (carriers and battleships) will give the U.S. a major victory. The Japanese will achieve a major victory if they sink 2 of the 3 U.S. carriers and destroy the airbase at Midway, forcing the remaining U.S. ships to retreat; and a decisive victory if they sink all 3 U.S. carriers and destroy the airbase at Midway, which paves the way to land the troops and take control of the island and the Pacific theatre. Alternatively, each unit in the game has been given a Victory Point value. The game can be played to 10 or 12 Victory Points (recommended), depending on the length of game you want. If both sides achieve the required points in the same turn, the side with more points wins the battle.
It plays similar to Guadalcanal in mechanics, but it has a few changes. I think balance is good since the Japanese player has to locate targets before attacking the zone. The US does win. I would say that testing different tactics as the Japanese is key to winning for them. Just like BOTB, if you make a bunch of costly moves at the beginning, you have little chance to recover. Very quick turns. Both players are involved at the same time like GC. I do think that many more eyes and minds on the game could help tweak that just like any other game like this. If you like Guadalcanal and Battle of the Bulge, it has a very similar feel. If you’re strictly about global games and larger units, this may be your thing. If there are any rules updates that need to be made, I will make them available.
