A good buy for $4. Simple, yet varied enough on large boards to avoid repetition of the greeble surface. Tiles connect seamlessly if you keep the shadows going in the same direction. While is looks a bit simplistic for what it is, this is to its benefit in my opinion. I too would like to see some laser turrets as a mini expansions for the play surface. I would also like to see some simple greeble structures to put into play as blocking obstacle terrain that serve no other purpose than board dressing.
