Well I have just run a post apocalyptic game based in the FALLOUT PA Universe and using the original Rogue Trader Rules from 1987!
It was a six player game + me and the Games Master and was great fun with factions from the Brotherhood of Steel, NCR and Super Mutants all making an appearance. What made it even more interesting was that none of us had met before and the game was sorted out via the forums to take place at Oldhammer Day!
Overall we had a really good time and I felt we were able capture a little bit of Fallout on the table top!
I have done a more comprehensive battlereport on my blog at: My Blog
Here are some photos for your viewing pleasure!
