I think this is a really cute look a clockworks, typically I think of them as something alien rather than human which leads to a sort of prometheous effect on the creator. Forbidden knowledge, Frankenstein, tragedy, all that.
I gotta jump on the bandwagon here: the quantum state thing kinda threw me. It seems rather out of place with the rest of the sub. Is there not some other way to score that doesn't require something that...advanced? Not all steampunk is going to be advanced enough to know of, let alone deal with quantum states. However, most steampunk will indeed have this sort of sporting event, at minimum around the Colleges of Steamtech.
As an alternative, perhaps something along the lines of 'keep-away'? For every minute you keep possession of the ball, you gain 2 points. First team to 10 wins (longer games can be played to 20, or even be timed, with the highest scoring team winning). I'll admit, the quantum state of existing and not-existing is an interesting variant of winning conditions, but I just find it too advanced for most steampunk settings. Go to Comment
Aetherball Systems (Technical/ Mechanical)
It's mostly designed for scientists of both the sane and mad variety to show off their inventions. In and of itself, it's not very steampunk, it's what the players bring to the field that make it so. Go to Comment
Nice application, good execution. Some of the ideas are a bit off for my liking, mostly the explosive bone growth bit. I can hang with bone sculpting and grafting, but I personally draw the line at dead things growing at a cellular level, magic or not. The names are inventive and fun, I enjoyed them. Go to Comment
