The biggest thing for me that I don’t see a lot of in other packs is having enough "special"rooms in these packs. I know that goes against the idea of modular but it would be great to have a set and build a castle that can easily have throne rooms, eating areas, jail/basements, chapels etc. that have slightly different architecture for the room.
Perhaps it’s just because I have 0 artistic abilities though and I’m a designer who wants plug and play. 
Looks good though, def. looks like a metal compared to marble. Any thoughts on having a few texture sets to get more mileage out of it for a game?
