For me it's the figure first then the rule set, so I've started out on my 15mm Sci-Fi project with making the figures look good (I hope). I've decided to use the 'Flames of War' style bases, mainly because I like the look of the rounded corners. These are Laser cut MDF ones from Warbases (http://www.warbases.co.uk/)
I already had these 'Alien' figures painted before starting this blog, so no before pics, sorry.
Here's a bunch of 15mm Khurasan Space Demons (http://khurasanminiatures.tripod.com/) based on Warbases FOW size bases
