Ooo blades is my favourite game system. It was my longest running campaign and we actually finished it. They ended up accidentally summoning a demon which burned half the city before containing it and using that to threaten the government into giving the poor more rights.

I’ve got a few waiting in the wings to play at some point. The main one I want to try is the Wildsea. I’ve got to finish Spire and possibly Heart before moving into a new system first though. Depending on how many demons my players end up summoning the spire game could end quite quickly.
