I've just completed an enjoyable adaptation of the popular board / miniatures game Memoir 44 using my Star Wars Risk figures to play the Pegasus Bridge scenario.
A close fought game in which the Republican assailants had the initial upper hand but were in the end defeated by stiff CIS resistance. It looked really good using my Eastern Front terrain tiles and the winter board.
I'm experiencing a bit of a Borg game phase as I recover from a long term illness. The games are easy to play, are visually excellent with miniatures, highly adaptable to any period and great for solo play.
I've accumulated Memoir 44 and the expansions for the Eastern Front, Mediterranian and Pacific Theaters, Command & Colours, Ancients and Napoleonic and Battle Cry.
My other adaptation on Memoir 44, which I playtested a number of times, was a version of the popular World of Tanks on-line game using the tank miniatures in the boxed set and differentiating Light, Medium, Heavy, TD and SPGs with 9 per side. This worked brilliantly and the games, despite played solo, had me gripped to the very end.
