yeah, share away if you want.
on a similar topic, i came across a nice defence a few days back. a base built in a river, with triangular water traps around the foundation. so basically, there were just triangular gaps around the base that prevented you getting close enough to the wall to hit it. due to the depth, i couldn't jump out, and they had been upped to stone, so i couldn't even jump out;)
i think i may have come across the same building, tall tower with a bridge to either side? and the bridges had triangle floors sticking out? like spikes?.
