There has been quite a bit of stuff going on for 15mm sci fi of late. The ranges from http://khurasanminiatures.tripod.com/ look especially interesting.
I’ve been looking at both the Gruntz and Tomorrows War rules – opposite ends of the spectrum to my mind. Of the two it’s TW that is grabbing my attention right now, having played Force on Force. The rather harder edge seems to appeal to my intent with this.
My interest was sparked by watching the film Elysium and a how such a setting could build into a campaign.
