My first add-on (besides BRSSEBz tuts) will be a powered barge. There will be several forms, one is a troop carrier, one a drive-on ferry, and one will be a tomahawk platform. If i feel like it, I may even make one that is all of the above. Here is an early o2 model of the barge (with some terrible pilothouse textures, hey, it is my first one), and the early model of the tomahawk missile.
One question. How do you make a turret that fires missiles?
