I remember Ysgarth from my role playing days in the late 1970s. The game first was published in 1979. It was one of a number of fantasy rpgs that I remember we tried before finally settling on the Warhammer Fantasy Role Play.
Ysgarth has got a pretty complex system of skills and attributes, but action is resolved on a simple d100 (that is, you roll 2d10s and read them as separate decimals)
Napoleon at Chattanooga is a free print-and-play board game. The authors write:
Napoleon at Chattanooga (NaC) is a painstakingly-researched, meticulously accurate simulation of Napoleon’s campaign in the Tennessee Valley. It is also a two-player game of exploration and conquest in the Solar System, which is also painstaking but not necessarily accurate.
Axemen and Allies is an fantasy/medieval variant for Axis and Allies.
DragonRune: Arena of Death is a set of rules for fantasy gladiatorial combat.
The second edition of One Page Fantasy Skirmish has been released.
