A few months ago I started working on a gaming table little by little, by the following parameters:
-Clear playability for
40K, meaning usability and clarity for playing purposes.
-Easy to pack away, light and durable.
-A coherent theme with a gamemat.
-Maximum gains with minimum effort.

I mostly used readymade stuff, but some pieces I just made myself by combining bitz, finnfoam and whatnot. I made use of the Ruined Sector set by Mantic Games which I find is a great value kit. Most of the time was spent on shading (see rightmost pic on 4th row with the rocks compared to the ones printed on the mat) and some pieces I painted multiple times before I was satisfied with the result. In the buildings I did some rust, wear, dirt and blackening from burning.
The idea as mentioned above is not a showcase level presentation as I have no time nor interest for such a thing as I also work on my miniatures, but the table is now in a phase inwhich I can call it playable on. With time I can focus on little details and add more during the years. For the base I just have a 6x4 table made from plywood that's supported by wooden frames, which can be locked in place with bolts.*
Basically you could make a table like this in about 4 days. In the bottom there's some pics with my Raptors, of which I got a separate thread in my sig. I hope you dig.
