Plastic Legions has some photos of a terrific skirmish battle board of some ruins set aside a sea. Wonderful stuff. I’d love to play a pirate skirmish game on this.

World War II Role Playing Game
The World War II RPG by Mikko Kauppinen is designed as a simple game that is deadly to low level characters, but that allows more powerful characters to do very cinematic actions. Characters have three attributes and a number of skills. Action resolution is done by rolling 1d6, subtracting the result from the relevant attribute and adding one. If the result is more than zero, the character has succeeded, and bigger numbers mean greater successes.
