The Armchair General writes:
A GLORIOUS VICTORY (AGV) is a reasonably quick and easy set of wargames rules designed for the period of warfare from around the early 15th century through to the latter part of the 16th century, thus covering the War of the Roses and most of the Renaissance period.
In 1975, Don Lowry released a set of rules called Grand Army. Designed for 9mm !? and 15mm figures, it allows players to recreate large scale battles for Napoleonics and the American Civil War. Grand Army now is available online.
Outland Games presents “Fast Play Mech Rules.” As with a roleplaying game, you begin by rolling up a mech. The entire set of rules occupies just one page.
Glory In The Arena is a set of rules for playing gladiatorial combat with 54mm figures.
