Mayday (GDW, 1978) won the Charles S. Roberts Award in 1978 for the Best Science-Fiction Board Game. On this snowy weekend in January I played the game as part of my 2019 CSR Wargame Challenge. As a longtime Classic Traveller RPG player and more recent fan of the Cepheus Light: Old-School Rules-Light 2D6-Based Sci-Fi Role-Playing Game it was interesting to see just how Mayday’s take on the Traveller RPG universe was different even back then. The differences in the setting means Mayday is not true to the Traveller RPG universe but makes the game challenging and fun in its own way.
Mayday uses a simple vector movement system adapted from Classic Traveller Book 2: Starships. The major setting difference in this case is in the technology used to express Small Craft. In Traveller, small craft are usually propelled by the M-Drive. As described in Traveller 5:
M-Drive: Maneuver is the standard in-system ship drive. It interacts with gravity sources to produce vector movement. It requires a separate power plant. (T5 p. 323)
Power plants in turn are usually fueled for for two weeks. For the purposes of a Mayday scenario this means a ship has unlimited maneuverability. However, in Mayday the Small Craft found on p. 13 are rated in terms of G Level; the maximum acceleration in a movement phase and the total acceleration allowed. For example, the classic Fighter is rated “4G12” which means it can burn up to a maximum 4G in a movement phase but can only make a total of 12G of vector changes before it is out of fuel. In Traveller 5 terms this looks like the Fighter is equipped with Rockets (“Chemical fuels combine in an exothermic reaction in a combustion chamber to produce thrust. Rockets are high volume fuel users”). Rockets are the lowest-Tech Level drives represented in the Traveller/Cepheus Engine rules – and even then in certain setting-specific versions (like Orbital 2100).
The implication of this technology limit for Small Craft means maneuver must be a carefully considered choice. This makes Mayday a much more interesting game with a bit of resource management.
In Mayday there is only one energy weapon, the Laser. This single Mayday weapon covers all the energy weapons found in Traveller/Cepheus Engine; Pulse Laser, Beam Laser, Particle Beam, Plasma Beam, Fusion Beam. This simplification may be in part because Mayday does not use any armor on ships. In this game, ships are small and fragile.
Surprisingly, Mayday has a complete section on building customized missiles. Players can design missiles with different guidance packages, propulsion options, warheads, and fuel. This is far more in depth than what is found in Traveller/Cepheus Engine where there are three classes of missiles; Regular Missiles, Smart Missiles, and Nuclear Missiles.
Many people criticize the computer rules in the Traveller universe as “wrong.” After all, in this day of iPads and miniaturized computing, how come shipboard computers are rated in terms of displacement tons (13.5 to 14 cubic meters depending on the rules version used). In Mayday, like Classic Traveller, computers are rated in terms of CPU and Storage. The CPU rating is how many programs the computer can run simultaneously while Storage is the number of programs that are “loaded” in the computer. This leads to challenging game decisions. When flying my little Free Trader running a Model/1 computer (CPU 2 / Storage 4) I need make sure the right programs are in memory to be used during the turn. I may have the right program on hand, but my computer is too small to keep everything loaded and ready. Larger military ships like the Destroyer with a Model/2 bis (CPU 6 / Storage 6) don’t have as many constraints (and access to many more advanced programs too).
Although Mayday is not “true” to the commonly accepted Classic Traveller/Cepheus Engine rules the differences make for a more interesting game. Incredibly, it’s all because of the technology chosen.

Cool, nice insight into Mayday (which I’ve never played) and how it compares to CE / CT. I think thats what make the Traveller-related games (such as Snapshot) interesting in that they have sight variations but have the ‘guts’ of CT in them.
Wow, nice travel back in time. Thanks for sharing.
