Thanks for the comments re' the minis
I think regards the gaming system Pulp can fit any time period very well, we were also considering a Dark Ages game.
With regards the Future Wars I'd had the minis sitting in boxes unused for a few years having tried and not been happy with other period specific rules sets. I think from past systems I've seen Necromunda was the best but its hard to stay enthused about unsupported rules sets. The fact that even the rules for vehicles are generic means that they fit in well with 1920's through to Future Wars games.
Fast play, fun, effective characterisation, no dodgy rules that favour particular 'types' and an workable 'campaign' mechanism make it a really adaptable, enjoyable set of rules to use.
