I printed off the FUBAR rules and lots of the supplements. I am also considering strongly getting Gruntz, as many have suggested. These will probably work for the first phase, where I am not looking at having more than a few squads of infantry and a vehicle or two. Later, I may get 5150: Battalion Command or Future Commander.
Looking at minis, I am getting closer to a decision. I like Khurasan's Federal Army and their Felids a lot. I wish I could see more painted examples of Ground Zero Games' minis. Rebel Minis is tempting, too. I will be getting Chuhuac. I am torn on the Ion Age Prydians. I think I will avoid bug hunts for now, so no worries there.
