As someone who is mostly on the "Painting" side of the hobby, my main outlet for actually playing 40k at the moment is against Ewan, my eldest son, who is pretty fond it as a way of wasting a wet afternoon. The big problem we've had though, is terrain, which has left us fighting over battlefields made of shoe boxes, bits of racetrack, and action-figure statuary. And to be honest I'm not forking out for "proper" scenery for sporadic, knock-about games.
So, one solution that was suggested was paper-craft terrain. Oho! I thought. So, following a recommendation I ended up at World Works Games, which makes loads of them, and bought the Mars Station set.
Now I remember how dreadful I am at Papercrafting. Thankfully, as pdfs, I can reprint the damn things. So, a couple of hours of pritt-stik-ing my fingers together and I've got some base tiles and a difficult terrain tile, and a little crawler unit thing:
The set also comes with modular wall pieces so I can make a couple buildings to go with them, so thats the next job, whilst I'm waiting for my Storm Talon order to turn up.
