A second post in a day - no that's not the Good Bit. The Good Bit is the return of Little Wars TV over on YouTube.
Little Wars TV does Gettysburg
The group who produce this includes the author of Altar of Freedom (Greg I think), a great set of grand tactical rules for the ACW. My old school buddy, Tony (who appropriately amassed an impressive 'Old School' collection) and I 'did' days one and two of Gettysburg a couple of years ago using AOF. In our scenario, day two took where we left off on day one rather than use the historical starting positions. I think we decided that the Rebs would have been all but spent after our day two so didn't go onto a third day.
All figures and terrain (mainly Baccus and Tiemcast/Leven) were painted or made (fences and trees) by Tony. Great use of an old felt cloth suitably spray painted in parts, and very effective looking masking tape roads.
Anyway, back to the original point, if you haven't already watched Little Wars TV, it's well worth having a gander.
