Doom: The Next Chapter is both an RPG, and a tabletop strategy game based in the Doom universe. It is a great example of how role playing mechanics can carry over to miniatures gaming.

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.
