I was just thinking about how the last few years we have gotten a nice new castle, following in a tradition of the classic castles and being able to be joined with other fortifications. Perhaps it would be nice to continue another old classic tradition and have some small to medium fortifications like these from the past to connect with it.
I own many of the new 2007 and 2008 sets but do not own the new Tower Raid but from what I can tell it lacks the connection parts to join it to the castle. I'd love to see some walls in particular but tower modular sets as well for castle fortifications.
When I was younger ten or there about I bought 4 of the knight's strongholds set. I made a few tall towers and some small modifications and used it as my main baddies castle for a while. The amount of variation in these sets lends themselves to all sorts of interesting possibilities and creating much larger castles and town walls is nice as well. I eventually merged two of the knight's strongholds to the dungeon masters castle as an outer defence and used the other two as a smaller fortress.
I can see gate houses, towers, wall sections all of types smaller structures as being a nice addition to the many exisiting castles and such made. I think for official Lego sets they could be very useful. In part as they can be used together and taken apart with ease as well as it almost encourages one to buy multiples of the smaller and medium fortifications so as to make bigger walls and towers etc. Just wanted to see what others thought of this idea. It could easily be used for building non-military structures as has been seen in the new town structures.
We have some awesome siege engines.... we need something fun to shoot at!
