-                At launch, I want to either show a list of games in progress, the current game, or the game creation screen.
-                - if a live game is in progress, immmediately go to that game. Such a game will be classified at game creation, so it should be persisted to the state.
-                - if no live games are in progress, but there are slow games in progress, show a list of the slow games and let the player choose which one to jump into.
-                - if no games are in progress, show only the game creation screen
-                - game creation menu should be present both when there are only slow games and when there are no games
-                - the UI returned here will always be available in other places, such as when the user is viewing a game and wants to return to this page
-
-                For the initial version, I want only to show the game creation screen. Then I will backtrack record application state so that the only decisions can be made.
