I have translated (not very well) in English "Argad!" my 28 mm skirmish rules.
I first wrote and published these game rules in 1996 and I am now updating them, it is in permanent evolution.
It is a simple system based on 6-sided dice but many tactical modifiers add flavour to the game. Movements are simultaneous, we call that " good-humoured simultaneity".
Some people like it because it is simple and fast.
Some people dislike it because it looks too simple and they don't like simultaneity, but even they often accept that it can be an interesting ruleset for the initiation of newcomers.
Do not play it for championships, or with competition-minded players, or on a a bare plain. It needs a large battlefield with plenty of obstacles, a good-humored team, and some role-playing mind.
