[ ] Can I use html template's and sub-composing to do composing of boardgame-component templates more directly? https://www.polymer-project.org/3.0/docs/api/utils/html-tag Currently it does a weird hoisting and insertion thing, but it might be simpler to just have the subcomponent string returned
[ ] Make it so all examples (and stubs) import {PolymerElement, html} at once instead of doing two separate imports
[ ] Player-info stub can lose the properties() block, right?
