Opinion of GW will always be, shall we say, divided.
The new starter sets however do have things going for them.
Number 1, the box makes simple terrain. I love the cargo containers. They'll fit in with my old 2nd Ed terrain next time I set them up.
The snap fit figures are nice as well. I know the later box sets may have more options but I have enough there to add to the Dark Imperium box set to have a decent Primaris set up.
Now, do I consider picking up another four mats to have enough for a 6ft x 4ft table? Has to be cheaper and easier to store than a Sector Imperialis.
