It is not about the decoration and minifigures on the set(s), but to me the modular is more meaningful. And perhaps, de-marco is also not the first one who created this modular town shape. Somehow, this concept again and again trigger me to comment that this idea is really cool!
I really hope if Lego could introduce this type of build to the collectors, compare to current non-standardize build. Sometime i really headache on how to decorate those Lego (especially Star Wars sets) even they all from same scenery, due to the odd tiles design.
