In this case, I bought the Ruins of Osgiliath; three sets for £40. I was astonished by the size of the box; opening it confirmed that the impression - these are huge and chunky. There's a reassuring weight to them and it seems clear they'll stand up to the rigours of gaming.
They're also huge. Seriously, this box of 3 sets will cover a 4x4 table easily. Look at how big they are!
I am really pleased with this little lot. I'll have to get some paint on them, but the light grey white stone of Osgiliath shouldn't be hard. I'll probably build the other two sets with slightly different variations to maximise their use on the table. After all, these are great generic fantasy pieces for Dragon Rampant and could even be used in SF Games with some scatter terrain.
