i appreciate the craft and attention to detail going into all aspects of the game right now, but i wonder if things shouldn't be sloppier, more fluid, easier to change and discard - more experimental.
make it easier to change game mechanics, concepts etc. in a more agile way.
push a whole bunch of stuff out there and see what sticks, what people find most fun, and ruthlessly discard the unfun stuff - then repeat the process all over again. maybe in a sketchier, improvised, more wireframe like environment. make more significant changes more rapidly by simplifying production processes.
tho this could be what you are already doing/trying to do, and i should really shut up because i don't know anything and things are progressing as rapidly as possible.
