Lately, I have been doing some pragmatic stuff, working out how people will respond to you/items/etc. Still not sure if this will end up being fun (arrgh!) but it seems hopeful at this point, actually.
There are lots of little, detail type work to do to get things to work, and some fairly strange things to understand and work around in the design. Also, finding some small related bugs in vex engine.
Soon, you can trade gems with a homemaker!
