Games Workshop produced an enticing-looking kit of dark future cityscape gubbinz to help you decorate bases of larger models. Unfortunately they took the low road and made a cheap rip-off of their true Warhammer 40k City Buildings line
I am a great fan of busy bases teeming with crushed vehicle parts, bones and the like. I have a pretty large bits box so getting parts is not usually a problem. I was still looking forward to check out the new box from GW.
At first the new bits look like parts from the existing GW kits: the City Buildings line and the ancient battlefield accessories sprue. Unfortunately they didn't use the original CAD designs but went for the dumbed-down, low-resolution version. What we got is the cheap-toy-like quality known also from the Age of Sigmar terrain.
Not only the elements are more crude, with unfinished-looking, shallow grooves and bevels but you can even see CAD artefacts to the point that the barrels are not cylinders but polygonal prisms.
In the end it's better to cut one of the City Buildings kits or the Munitorum Armoured Containers set than use the Sector Imperialis Large Base Detail Kit. Note that the much better quality Manufactorum costs exactly the same and gives you more bits.
